DESCRIPTION
This manpage describes the various (config) files and their formats used by the tin(1) newsreader.

FILES

$MAILCAPS
${TIN_HOMEDIR-"$HOME"}/.mailcap
/etc/mailcap
/usr/etc/mailcap
/usr/local/etc/mailcap
/etc/mail/mailcap

    mailcap(4) files as defined in RFC1524. The Mailcap files are read by tin(1) to determine how to display non-text messages at the local site. Any line that starts with "#" is a comment. Blank lines are ignored. Otherwise, each line defines a single mailcap entry for a single content type. Long lines may be continued by ending them with a backslash character, "\".

    Each individual mailcap entry consists of a content-type specification, a command to execute, and (possibly) a set of optional "flag" values.

    The "type" field is simply any legal content type name. It is the string that will be matched against the "Content-Type" header to decide if this is the mailcap entry that matches the current message. Additionally, the type field may specify a subtype or a wildcard to match all subtypes.

    The "command" field is any UNIX command and is used to specify the interpreter for the given type of message. It will be passed to the shell via the system(3) facility.

    Semicolons and backslashes within the command or any flag field must be quoted with backslashes. If the field contains "%s", those two characters will be replaced by the name of a file that contains the body of the message. If it contains "%t", those two characters will be replaced by the content-type field, including the subtype, if any. If it contains "%{" followed by a parameter name and a closing "}", then all those characters will be replaced by the value of the named parameter, if any, from the Content-Type header. Finally, if the field contains "\%", those two characters will be replaced by a single "%" character.

    Besides the type and command field the following "flags" are defined:

    compose
        The "compose" field may be used to specify a program that can be used to compose a new body or body part in the given format. Its intended use is to support mail composing agents that support the composition of multiple types of mail using external composing agents. As with the view-command, the semantics of program execution are operating system dependent. The result of the composing program may be data that is not yet suitable for mail transport - that is, a Content-Transfer-Encoding may need to be applied to the data.

    composetyped
        The "composetyped" field is similar to the "compose" field, but is to be used when the composing program needs to specify the Content-Type header field to be applied to the composed data. The "compose" field is simpler, and is preferred for use with existing (non-mail-oriented) programs for composing data in a given format. The "composetyped" field is necessary when the Content-Type information must include auxiliary parameters, and the composition program must then know enough about mail formats to produce output that includes the mail type information.

    edit
        The "edit" field may be used to specify a program that can be used to edit a body or body part in the given format. In many cases, it may be identical in content to the "compose" field, and shares the operating-system dependent semantics for program execution.

    print
        The "print" field may be used to specify a program that can be used to print a message or body part in the given format. As with the view-command, the semantics of program execution are operating system dependent.

    test
        The "test" field may be used to test some external condition (e.g., the machine architecture, or the window system in use) to determine whether or not the mailcap line applies. It specifies a program to be run to test some condition. The semantics of execution and of the value returned by the test program are operating system dependent. If the test fails, a subsequent mailcap entry should be sought. Multiple test fields are not permitted - since a test can call a program, it can already be arbitrarily complex.

    needsterminal
        The "needsterminal" field indicates that the view-command must be run on an interactive terminal. This is needed to inform window-oriented user agents that an interactive terminal is needed. (The decision is not left exclusively to the view-command because in some circumstances it may not be possible for such programs to tell whether or not they are on interactive terminals.) The needsterminal command should be assumed to apply to the compose and edit commands, too, if they exist. Note that this is NOT a test - it is a requirement for the environment in which the program will be executed, and should typically cause the creation of a terminal window when not executed on either a real terminal or a terminal window.

    copiousoutput
        The "copiousoutput" field indicates that the output from the view-command will be an extended stream of output, and is to be interpreted as advice to the UA (User Agent mail-reading program) that the output should be either paged or made scroll-able. Note that it is probably a mistake if needsterminal and copiousoutput are both specified.

    description
        The "description" field simply provides a textual description, optionally quoted, that describes the type of data, to be used optionally by mail readers that wish to describe the data before offering to display it.

    textualnewlines
        The "textualnewlines" field, if set to any non-zero value, indicates that this type of data is line-oriented and that, if encoded in base64, all newlines should be converted to canonical form (CRLF) before encoding, and will be in that form after decoding. In general, this field is needed only if there is line-oriented data of some type other than text/* or non-line- oriented data that is a subtype of text.

    x11-bitmap
        The "x11-bitmap" field names a file, in X11 bitmap (xbm) format, which points to an appropriate icon to be used to visually denote the presence of this kind of data.

    nametemplate
        The "nametemplate" field gives a file name format, in which %s will be replaced by a short unique string to give the name of the temporary file to be passed to the viewing command. This is only expected to be relevant in environments where filename extensions are meaningful, e.g., one could specify that a GIF file being passed to a gif viewer should have a name ending in ".gif" by using "nametemplate=%s.gif"

    tin(1) currently only respects the "test", "description", "nametemplate" and partly the "needsterminal" flags, all other flags are internally ignored. It also can't handle the "%F" and "%n" expansions yet.

    Example:
        # mailcap file example
        image/*;\
        xv -8 -geometry +0 '%s';\
        description=%{name} %t-Image;\
        test=test "$DISPLAY" \
        nametemplate=%s.IMAGE

        message/rfc822;\
        if test -x /usr/bin/less \;\
        then less '%s' \;\
        else more '%s' \; fi;\
        edit=${EDITOR-vi} '%s';\
        compose=${EDITOR-vi} '%s';\
        print=a2ps %s;\
        needsterminal

/etc/nntpserver

    default NNTP-server to read news from if not reading from the local spool. '-g server', $NNTPSERVER have higher priority (in that order), the default server given at compile time has lower priority.

${TIN_HOMEDIR-"$HOME"}/.newsauth

    "nntpserver password [user]" pairs for NNTP servers that require authorization. Any line that starts with "#" is a comment. Blank lines are ignored. This file should be readable only for the user as it contains the users uncrypted password for reading news!

    nntpserver
        full qualified domain name of the newsserver.

    password
        users uncrypted password for reading news.

    user
        username on the newsserver if it differs from the local login. this field is optional.

    Example:
        # sample .newsauth file
        news.example.org example
        news.example.net news guest

${TIN_HOMEDIR-"$HOME"}/.newsrc

    "newsgroupflag [article[,article | -article]...]" lines.

    newsgroup
        the name of the newsgroup.

    flag
        a flag indicating if the group is subscribed ':' or not '!'.

    article
        range of already read articles from that group; numbers separated by commas with sequential numbers collapsed with hyphens.

    Example:
        # sample .newsrc file
        news.software.b! 1-666,669
        news.software.nntp: 1-13245,13247,13249
        news.software.readers: 1-19567,19571-19597

    newsgroups index files

${TIN_INDEX_SAVEDIR-"${TIN_HOMEDIR-"$HOME"}/.tin"}/.save/

    saved newsgroups index files

${TIN_HOMEDIR-"$HOME"}/.tin/active.mail

    active file ("mail_group_name maxnum minnum mailspool"-pairs) of user's mailgroups (requires tin(1) to be build with mh-mail-handling support).

    mail_group_name
        must be the pathname of the mailbox relative to field #4 with / changed to .

    maxnum
        just put a large number here, something higher than the highest message in the mailbox

    minnum
        put 0 here

    mailspool
        path of mail spool directory. This must be the full pathname to the root of the mail folder area.

    Example:
        Mail.inbox 12345 00000 /home/foo
        Mail.outbox 23456 00000 /home/foo

    This allows access to the 'inbox' and 'outbox' folders of user foo. They are accessed via /home/foo/Mail/inbox and /home/foo/Mail/outbox

${TIN_HOMEDIR-"$HOME"}/.tin/active.save

    active file of user's saved newsgroups, used by tin -R.

/etc/tin/attributes
${TIN_HOMEDIR-"$HOME"}/.tin/attributes

    The group attributes files may be used to override some global settings from ${TIN_HOMEDIR-"$HOME"}/.tin/tinrc on a per group basis. Order is important as last match counts; this allows to refine attributes for narrowed scopes. Note that the scope=<grouplist> line has to be specified before the attributes are specified for that list. All attributes are set to a reasonable default so you only have to specify the attribute that you want to change. All toggle attributes are set by specifying ON/OFF. Otherwise, they function exactly as their global equivalents. The following group attributes are available:

    scope
        This changes the list of groups to which the attributes that follow will be applied. See the section NEWSGROUP LISTS & WILDCARDS in tin(1) for the types of pattern that can be used here.

    auto_save
        Identical to the tinrc variable of the same name

    auto_select
        Automatically perform the GroupMarkUnselArtRead ('X') command after entering the group.

    batch_save
        Can be used to override the global setting in tinrc on a per group basis. For more information read section AUTOMATIC MAILING AND SAVING NEW NEWS in tin(1).

    delete_tmp_files
        If this is set to ON, then saved article files that have been post-processed will be automatically deleted, otherwise the user will be asked whether to delete the post-processed files. Automatic processing of marked articles using GroupAutoSave ('S') will suppress prompting.

    fcc Mailbox to save sent mails. The format of the mailbox is controlled via the tinrc mailbox_format variable.

    followup_to
        Set ''Followup-To:''-header to the specified group(s).

    from
        Identical to the tinrc variable mail_address

    maildir
        Identical to the tinrc variable default_maildir

    mailing_list
        Used when a group is a mailing list. All responses to the group will be directed to this email address instead

    mime_forward
        Determines whether usenet articles are forwarded as attachment or inline. When set to OFF, the forwarded article will be included in the body of the mail, while setting this variable to ON will cause the article to be attached as a separate MIME part. Enabling mime_forward is particularly useful for articles consisting of multiple MIME parts such as PGP/MIME signed messages or being encoded in a different character set than your local one. It is also useful if the receiver should be able to operate on the entire forwarded article (i.e., view or save it without your comments). On the other hand, if you want to forward only some parts of the article or to insert 'inline' annotations, you might want to disable this option. Please note that for this option to have effect, the tinrc variable interactive_mailer has to be set to 0 (which is the default).

    mime_types_to_save
        A comma separated list of MIME major/minor Content-Types that will be saved when using the view/save and save/autosave features. A single * can be used to wildcard the major and/or minor type and a ! as the first character in an entry will negate it, eg: image/*,!image/bmp,!text/html. Default is */*

    news_quote_format
        Identical to the tinrc variable of the same name

    organization
        This can be used to set the article header field ''Organization:''. It overrides the setting (if any) of organization in /etc/tin/tin.defaults and $ORGANIZATION (or $NEWSORG on Apollo DomainOS). Note that some newsserver might still overwrite the ''Organization:''-header.

    post_proc_type
        Identical to the tinrc variable post_process_type

    quote_chars
        Identical to the tinrc variable of the same name

    savedir
        Identical to the tinrc variable default_savedir

    savefile

    show_author
        Identical to the tinrc variable of the same name

    show_info
        Identical to the tinrc variable of the same name

    show_only_unread
        Identical to the tinrc variable of the same name

    sigfile
        Identical to the tinrc variable default_sigfile

    sort_art_type

    thread_arts
        Identical to the tinrc variable thread_articles

    thread_perc
        Identical to the tinrc variable thread_perc

    x_body
        A piece of text that will be added at the start of a message body. If this string starts with a / or ~ then it is assumed to be the name of a file containing the text to insert.

    x_comment_to
        Insert ''X-Comment-To:''-header, this is only useful in FIDO groups.

    x_headers
        A string including header-name and the contents of the header that will be automatically added when posting. If the string starts with a / or ~ then it is assumed to be the name of a file containing the header and its content to be inserted. If the string starts with a ! then what follows is assumed to be the path to a program to be executed to generate the header and its content.

    quick_kill_scope
        A comma-separated list of newsgroup patterns (wildmat-style) to which groups the filter rule added by QuickFilterKill will be applied. If unset the default from the tinrc variable default_filter_kill_global will be used.

    quick_kill_expire
        Identical to the tinrc variable default_filter_kill_expire

    quick_kill_case
        Identical to the tinrc variable default_filter_kill_case

        Identical to the tinrc variable default_filter_kill_header

    quick_select_scope
        A comma-separated list of newsgroup patterns (wildmat-style) to which groups the filter rule added by QuickFilterSelect will be applied. If unset the default from the tinrc variable default_filter_select_global will be used.

    quick_select_expire
        Identical to the tinrc variable default_filter_select_expire

    quick_select_case
        Identical to the tinrc variable default_filter_select_case

    quick_select_header
        Identical to the tinrc variable default_filter_select_header

    ispell
        Path and options for ispell(1)-like spell-checker, e.g. "aspell --mode=email --dont-backup check"

    mm_network_charset
        Identical to the tinrc variable of the same name

    undeclared_charset
        Assume (broken) articles without MIME charset declaration have this charset - default is US-ASCII. This attribute works only on systems with working iconv(3), others might have to compile tin(1) with --disable-mime-strict-charset.

    Example:
        # include extra headers
        # assume ISO-8859-1 as charset if no charset is declared
        scope=*
        x_headers=~/.tin/headers
        undeclared_charset=ISO-8859-1
        # in *sources* set post process type to shar only
        scope=*sources*
        post_proc_type=1
        # in *binaries* turn on full post processing,
        # remove tmp files and set Followup-To: poster
        scope=*binaries*
        post_proc_type=2
        delete_tmp_files=ON
        followup_to=poster
        # in fido.* newsgroups change quote_chars
        # and add X-Comment-To: line
        scope=fido.*
        quote_chars=%s>_
        x_comment_to=ON
        # in *.test newsgroups, don't append signature
        # and preset Subject
        scope=*.test
        sigfile=--none
        x_headers=Subject: test - ignore - no reply
        # assume ISO-2022-JP-2 as charset
        scope=fj.*,japan.*
        undeclared_charset=ISO-2022-JP-2

${TIN_HOMEDIR-"$HOME"}/.tin/filter

    The filter file is used to assign scores to certain articles. Based on the score an article can be filtered out (hidden) or marked hot. Empty lines or lines beginning with a '#' are ignored.

    comment
        Every entry (rule) in the filter file might get a comment. Multiple lines are allowed (but only for comments yet). Every line must start with the "comment="-keyword. Comments must appear first in the rule. Comment lines placed within a rule will be moved to the begin of the next rule. This might be changed in the future. Don't use '#' to mark comments as those lines are ignored and your comments will get lost on the next write of the file.

    group
        A comma-separated list of newsgroup patterns (wildmat-style) to which groups the filter rule will be applied. This line is mandatory!

    case
        0=case-sensitive, 1=case-insensitive

    score
        Score value of the rule; can also be one of the magic words "kill" or "hot".

    subj
        Match against ''Subject:''

    from
        Match against ''From:''. tin(1) converts the contents of the ''From:''-header to an old style e-mail address, e.g. ''some@body.example (John Doe)'' instead of ''John Doe <some@body.example>'', before trying to match the patterns in the filter rule.

    msgid
        Match against ''Message-ID:'' and full ''References:''

    msgid_last
        Match against ''Message-ID:'' and last ''References:'' entry only

    msgid_only
        Match against ''Message-ID:''

    refs_only
        Match against ''References:''

    lines
        Match against ''Lines:'', <num matches less than, >num matches more than.

    gnksa
        Match against ''From:''-address parser return codes.

    xref
        Match against ''Xref:''-line. Before any matching is done the line is turned into the same format ''Newsgroups:'' has that is it is turned into a comma separated newsgoup list with all other informations (i.e. the article counter) removed.

    time
        time_t value when rule expires

    Example:
        comment=mark all articles about tin, rtin,
        comment=tind, ktin or cdtin as hot
        group=*
        type=1
        case=1
        score=hot
        subj=\b(cd|[rk]?)?tin(d|pre)?[-.0-9]*\b

    default_select_pattern

    default_shell_command

    default_sigfile
        The path that specifies the signature file to use when posting, following up to or replying to an article. If the path is a directory then the signature will be randomly generated from files that are in the specified directory. If the path starts with a ! the program the path points to will be executed to generate a signature. tin(1) will pass the name of the current newsgroup as argument to the program. --none will suppress any signature. Default is ${TIN_HOMEDIR-"$HOME"}/.Sig.

    default_subject_search

    draw_arrow
        Allows groups/articles to be selected by an arrow '->' if set ON or by an highlighted bar if set OFF.

    force_screen_redraw
        Specifies whether a screen redraw should always be done after certain external commands. Default is OFF.

    getart_limit
        If getart_limit is > 0 not more than getart_limit articles/group are fetched from the server. If getart_limit is < 0 tin(1) will start fetching articles from your first unread minus absolute value of getart_limit. Default is 0, which means no limit.

        If ON catchup group when leaving with the left arrow key. Default is ON.

    groupname_max_length
        Maximum length of the names of newsgroups to be displayed so that more of the newsgroup description can be displayed. Default is 32.

    hide_uue
        If set to 'No' then raw uuencoded data is displayed. If set to 'Yes' then sections of uuencoded data will be shown with a single tag line showing the size and filename (much the same as a MIME attachment). If set to 'Hide all' then any line that looks like uuencoded data will be folded into a tag line. This is useful when uuencoded data is split across more than one article but can also lead to false positives. This setting can also be toggled in the article viewer. Default is 'No'.

    inews_prog
        Path, name and options of external inews(1). If you are reading via NNTP the default value is "--internal" (use built-in NNTP inews), else it is "inews -h". The article is passed to inews_prog on STDIN via '< article'.

    info_in_last_line
        If ON, show current group description or article subject in the last line (not in the pager and global menu) - ToggleInfoLastLine ('i' toggles setting). This facility is useful as the full width of the screen is available to display long subjects. Default is OFF.

    interactive_mailer
        If greater than 0 your mailreader will be invoked earlier for reply so you can use more of its features (e.g. MIME, pgp, ...). 1 means include headers, 2 means don't include headers (old use_mailreader_i=ON option). 0 turns off usage. This option has to suit default_mailer_format. Default is 0.

    inverse_okay
        If ON use inverse video for page headers and URL highlighting. Default is ON.

    keep_dead_articles
        If ON keep all failed postings in ${TIN_HOMEDIR-"$HOME"}/dead.articles besides keeping the last failed posting in ${TIN_HOMEDIR-"$HOME"}/dead.article. Default is ON.

    kill_level
        This option controls the processing and display of articles that are killed. There are 3 options:

        0   Kill only unread arts is the 'traditional' behavior of tin(1). Only unread articles are killed once only by marking them read. As filtering only happens on unread articles with kill_level set to 0, art_marked_killed and art_marked_read_selected are only shown once. When you reenter the group the mark will be gone.

        1   Kill all arts & show with K will process all articles in the group and therefore there is a processing overhead when using this option. Killed articles are threaded as normal but they will be marked with art_marked_killed.

        2   Kill all arts and never show will process all articles in the group and therefore there is a processing overhead when using this option. Killed articles simply does not get displayed at all.
    Default is 0 (Kill only unread arts).

    mail_8bit_header
        Allows 8bit characters unencoded in the header of mail message. Default is OFF. Turning it ON is effective only if mail_mime_encoding is also set to 8bit. Leaving it OFF is safe for most users and compliant to Internet Mail Standard (RFC2822 and RFC2047). Default is OFF.

    mail_address
        User's mail address (and full name), if not username@host. This is used when creating articles, sending mail and when pgp(1) signing.

    mail_mime_encoding
        MIME encoding of the body in mail message, if necessary (8bit, base64, quoted-printable, 7bit). Default is 8bit and no encoding (or charset conversion) is performed (i.e., local charset is used as it is).

    mail_quote_format
        Format of quote line when replying (via mail) to an article (%A=Address, %D=Date, %F=Fullname+Address, %G=Groupname, %M=Message-ID, %N=Fullname, %C=Firstname, %I=Initials). Default is "In article %M you wrote:"

    mailbox_format
        Select one of the following mailbox-formats: MBOXO (default, except on SCO), MBOXRD or MMDF (default on SCO). See mbox(5) for more details on MBOXO and MBOXRD and mmdf(5) for more details about MMDF.

    mark_saved_read
        If ON mark articles that are saved as read. Default is ON.

    mark_ignore_tags
        When this is ON, the GroupMarkThdRead, ThreadMarkArtRead functions ('K') mark just the current article or thread, ignoring other tagged, unread articles. When OFF, the same function presents a menu with choices of the current thread or article, all tagged, unread articles, or nothing.

    metamail_prog
        Path, name and options of external metamail(1) program used to view non-textual parts of articles. To use the built-in viewer, set to --internal. This is the default value when metamail(1) is not installed. Leave it blank if you don't want any automatic viewing of non-textual attachments. The 'V' command can always be used to manually view any attachments. See also ask_for_metamail.

    mm_charset
        Charset supported locally, which is also used for MIME header (charset parameter and charset name in header encoding) in mail and news postings. If MIME_STRICT_CHARSET is defined at the compile time, text in charset other than the value of this parameter is considered not displayable and represented as '?'. Otherwise, all character sets are regarded as compatible with the display. If it's not set, the value of the environment variable $MM_CHARSET is used. US-ASCII or compile-time default is used in case neither of them is defined. If your system supports iconv(3), this option is disabled and you should use mm_network_charset instead.

    mm_network_charset
        Charset used for posting and MIME headers; replaces mm_charset. Conversion between mm_network_charset and local charset (determined via nl_langinfo(3)) is done via iconv(3), if this function is not available on your system this option is disabled and you have to use mm_charset instead. mm_network_charset is limited to one of the following charsets:
        US-ASCII, ISO-8859-{1,2,3,4,5,7,9,10,13,14,15,16}, KOI8-{R,U,RU} EUC-{CN,JP,KR,TW}, ISO-2022-{CN,CN-EXT,JP,JP-1,JP-2}, Big5, UTF-8
        Not all values might work on your system, see iconv_open(3) for more details. If it's not set, the value of the environment variable $MM_CHARSET is used. US-ASCII or compile-time default is used in case neither of them is defined.

    mono_markdash
        Character attribute of words emphasized like _this_. It is depending on your terminal which attributes are usable. See also word_h_display_marks and word_highlight.

    mono_markslash
        Character attribute of words emphasized like /this/. It is depending on your terminal which attributes are usable. See also word_h_display_marks and word_highlight.

    mono_markstar
        Character attribute of words emphasized like *this*. It is depending on your terminal which attributes are usable. See also word_h_display_marks and word_highlight.

    mono_markstroke
        Character attribute of words emphasized like -this-. It is depending on your terminal which attributes are usable. See also word_h_display_marks and word_highlight.

    newnews
        These are internal timers used by tin(1) to keep track of new newsgroups. Do not change them unless you understand what they are for.

    news_headers_to_display
        Which news headers you wish to see. If you want to see _all_ the headers, place an '*' as this value. This is the only way a wildcard can be used. If you enter 'X-' as the value, you will see all headers beginning with 'X-' (like X-Alan or X-Pape). You can list more than one by delimiting with spaces. Not defining anything turns off this option.

    news_headers_to_not_display
        Same as news_headers_to_display except it denotes the opposite. An example of using both options might be if you thought X- headers were A Good Thing(tm), but thought Alan and Pape were miscreants... well then you would do something like this: news_headers_to_display=X- news_headers_to_not_display=X-Alan X-Pape Not defining anything turns off this option.

    news_quote_format
        Format of quote line when posting/following up an article (%A=Address, %D=Date, %F=Fullname+Address, %G=Groupname, %M=Message-ID, %N=Fullname, %C=Firstname, %I=Initials). Default is "%F wrote:".

    normalization_form

        0   None: no normalization

        1   NFKC: Compatibility Decomposition, followed by Canonical Composition

        2   NFKD: Compatibility Decomposition

        3   NFC: Canonical Decomposition, followed by Canonical Composition

        4   NFD: Canonical Decomposition
    Some normalization modes are only available if they are supported by the library tin(1) uses to do the normalization. Default is NFKC.

    pgdn_goto_next
        If ON the PageDown keys will go to the next unread article when pressed at the end of a message. Default is ON.

    pos_first_unread
        If ON put cursor at first unread article in group otherwise at last article. Default is ON.

    post_8bit_header
        Allows 8bit characters unencoded in the header of a news article, if set this also disables the generation of MIME-headers when they are usualy required. Default is OFF. Only enacted if post_mime_encoding is also set to 8bit. In a number of local hierarchies where 8bit characters are used, using unencoded (raw) 8bit characters in header is acceptable and sometimes even recommended so that you need to check the convention adopted in the local hierarchy of your interest to determine what to do with this and post_mime_encoding.

    post_mime_encoding
        MIME encoding of the body in news message, if necessary. (8bit, base64, quoted-printable, 7bit) Default is 8bit, which leads to no encoding. base64 and quoted-printable are usually undesired on usenet.

    post_process_view
        If ON, then tin(1) will start an appropriate viewer program to display any files that were post processed and uudecoded. The program is determined using the mailcap file. Default is ON.

    post_process_type
        This specifies whether to perform post processing on saved articles. Because the shell archive may contain commands you may not want to be executed, be careful when extracting shell archives. The following values are allowed:

        0   No (default), no post processing is done.

        1   Shell archives, unpacking of multi-part shar(1) files only. Because the shell archive may contain commands you may not want to be executed, be careful with this option.

        2   Yes, binary attachments and data will be decoded and saved.

    posted_articles_file
        Keep posted articles in ${TIN_HOMEDIR-"$HOME"}/Mail/posted_articles_file. If no filename is set then postings will not be saved. Default is 'posted'.

    print_header
        If ON, then the full article header is sent to the printer. Otherwise only the ''Subject:'' and ''From:'' fields are output. Default is OFF.

    process_only_unread
        If ON only save/print/pipe/mail unread articles (tagged articles excepted). Default is OFF.

    prompt_followupto
        If ON show empty ''Followup-To:'' header when editing an article. Default is OFF.

    quote_chars
        The character used in quoting included text to article followups and mail replies. The '_' character represents a blank character and is replaced with ' ' when read. Default is '>_'.

    quote_style
        This bit coded integer value controls how articles are to be quoted when following up or replying to them. Any of the following options can be combined by adding all relevant values. Default is 5, which means that quote characters are compressed and empty lines are quoted.

        1   Compress quotes Compress quote characters together when quoting multiple times (for example, '> > >' will be turned into '>>>'). This option is on by default.

        2   Quote Signatures This option is off by default. Signatures are always quoted regardless of this option when you are viewing an article in raw mode PageToggleHeaders ('^H') and followup or reply to it.

        4   Quote empty lines This option is on by default.

${TIN_LIBDIR-NEWSLIBDIR}"/"${TIN_ACTIVEFILE-active}

    This file lists the newsgroups that the local site receives. Each newsgroup should be listed only once. Each line specifies one group; within each newsgroup, articles are assigned unique names, which are monotonically increasing numbers.

    If an article is posted to newsgroups not mentioned in this file, those newsgroups are ignored. If no valid newsgroups are specified, the article is rejected.

    Each line consists of four space-separated fields "name highmark lowmark flags".

    name
        is the name of the newsgroup

    highmark
        is the highest article number that has been used in that newsgroup

    lowmark
        is the lowest article number in the group; this number is not guaranteed to be accurate, and should only be taken to be a hint. Note that because of article cancellations, there may be gaps in the numbering sequence. If the lowest article number is greater then the highest article number, then there are no articles in the newsgroup.

    flags
        can be one of those

        y   local postings are allowed

        n   no local postings are allowed, only remote ones

        m   the group is moderated and all postings must be approved

${TIN_LIBDIR-NEWSLIBDIR}/overview.fmt

    This file specifies the organization of the news overview database (see also newsoverview(5)). The order of lines in this file is important; it determines the order in which the fields will appear in the database. tin(1) currently only understands the order specified in RFC2980. See also overview.fmt(5). tin(1) only tries to read the file if you read directly from the local spool, if you read news via NNTP, tin(1) uses the LIST OVERVIEW.FMT (RFC2980) command instead.

${TIN_LIBDIR-NEWSLIBDIR}/subscriptions

    This file contains a list of newsgroups - one per line - which the client should subscribe to when the user has no ${TIN_HOMEDIR-"$HOME"}/.newsrc for the newsserver. tin(1) only tries to read the file if you read directly from the local spool, if you read news via NNTP, tin(1) uses the LIST SUBSCRIPTIONS (RFC2980) command instead.
