Overview
##############################################################################
cksfv (Check SFV) can create simple file verification (SFV) listings and test
already created SFV files.  Uses the crc32 checksum.

##############################################################################
Description
##############################################################################
Some files that you download will come with a .sfv file.  This is used to
verify that the files that you recieved are the same as the originals.
cksfv is a program that can use the .sfv file to verify the downloaded
files.  Also, it can be used to create new .sfv files.

##############################################################################
Examples
##############################################################################
Say you just downloaded some files and they came with .sfv file.  To verify
the files you can run the following command.  The output for the following
command is also shown.

        $ cksfv -f new_files.sfv
        --( Verifying file: new_files.sfv )-------------------------
        COPYING:        OK
        ChangeLog:      OK
        Makefile:       OK
        README:         OK
        cksfv:          OK
        ------------------------------------------------------------
        Everything OK

If you are getting a lot of errors looking like this:

        $ cksfv -f new_files.sfv
        --( Verifying file: new_files.sfv )-------------------------
        COPYING:        No such file or directory
        ChangeLog:      No such file or directory
        Makefile:       No such file or directory
        README:         No such file or directory
        cksfv:          No such file or directory
        ------------------------------------------------------------
        Errors Occured

You might want to try using the -i flag.  This ignores case on filenames.
Sometimes the .sfv file will have all the file names in uppercase and your
files will be all in lowercase.  This option will fix that problem.

        $ cksfv -f new_files.sfv -i
        --( Verifying file: new_files.sfv )-------------------------
        COPYING:        OK
        ChangeLog:      OK
        Makefile:       OK
        README:         OK
        cksfv:          OK
        ------------------------------------------------------------
        Everything OK
        
Now for creating your own .sfv files.  You can run the following command.

        $ cksfv * > mine.sfv

It will create a create a file that looks like:

Right now the files can only be access via http at
http://www.fodder.org/cksfv/.  I have a tarball and RPMs there.
