# check GNU info files in /usr/info. note that these have nothing to
# do with SBo .info files (those don't go in packages anyway).
#
# if /usr/info exists, it must have at least one *.info or *.info.gz
# file in it, and it must have 'dir' (which got created by doinst.sh;
# the preinstall test ensures /usr/info/dir isn't actually a regular
# file in the package).
#
# non-gzipped .info files cause warnings (non-fatal).
#
# content of 'dir' and each .info(.gz) file is checked, but not in
# great detail.
#
# if there are info files and a dir, check whether there's a douninst.sh to
# clean up on package removal... but it's just a "note", non-fatal, since
# we have thousands of packages that predate the existence of douninst.sh.
#
# this is more complicated than it should be because our file command
# doesn't recognize .info files (it just calls them "data", with MIME
# type "application/octet-stream"). all valid .info files that I've seen
# have the 0x1f character (US, unit separator), so we'll check for that.

# quite a bit faster than using the file command... though we could
