# Get rid of some perl module dependencies, replacing with stuff that's
# shipped with Slackware's perl package. Specifically:
# The obsolete Getopt::Mixed module is replaced by Getopt::Long.
# Date::Format is only used for ctime(), which is replaced by POSIX::ctime().
# Date::Parse is supposedly required, but is never used (removed it).
# For anyone reading this, no, this didn't break opf2mobi (it was
# already broken).

# lit2mobi calls convertlit by its old name, which might trigger
# stupid content filters. Replace with modern inoffensive name, in
# silly obfuscated way so this script doesn't contain the old name.
# (In case you're wondering, I'm not offended by this, I just don't want
# to get complaints from easily-offended people).

# It's pure Perl code (no shared libs), but not packaged as a perl module.
# We'll install the modules in the standard place for 3rd-party perl modules.
