SIZEify (maintainer timeout)

Use PLIST_FILES (bento-tested, marcus-reviewed).

Update to 2.0.5, which contains important fixes to the autorespond
exit code in various situations; previously, mail may have been lost
in some circumstances.

Update to autorespond-2.0.4, which contains a couple of security fixes.
This version also includes the Debian manpage, which I converted to
-mdoc format; the WITHOUT_MDOC_MANPAGE knob makes the port install
the original Debian page.

Fix an off-by-one error in strncpy(3) usage.
Unquote the comment variable.

PR:             55700
Submitted by:   Alex Dupre <sysadmin@alexdupre.com>

Update to 2.0.3 and add my autoconfiguration patch which uses DJB's
mechanisms for detecting the availability of strcasestr(3) and only uses
autorespond's own strcasestr() version if needed.

NOTE: there is NO functionality change in autorespond-2.0.3 with respect
to 2.0.2.

Remove pkg-comment files in my ports.

Add -E to REINPLACE because it's a extended RE

PERL -> REINPLACE
And some ports have USE_PERL5=yes now.

CC, CXX, CFLAGS, PTHREAD_CFLAGS and PTHREAD_LIBS may contain `/' in
them when using a non-default compiler/linker, so do not use `/' as
delimiter for s///. (I picked `|' instead)

Make the strcasestr() definition conditional on OSVERSION.   Respect CFLAGS by
patching them into the program Makefile.   No longer override the do-build
target, let make(1) do its thing.    

Update autorespond to 2.0.2, adding a patch to comment out   a definition of
strcasestr(), which is already provided by   our libc's <string.h>.    

Spaces->tabs in the mail category.    

Update md5sum of a rerolled (and otherwise unchanged tarball)    

Use an alternative MASTER_SITE to find the distfile.    

Convert category mail to new layout.
