+opencomal (interpreter for Comal programming language)
+
+OpenComal is a portable and free implementation of the Comal programming
+language written by Jos Visser. Currently supported platforms are Unix,
+MsDos and Win32. Comal is a crossover between Basic and Pascal, with
+the best features of both and none of the drawbacks of either.
+
+opencomal development stopped in January 2002. By default, this script
+builds the last stable release of opencomal. If you'd rather build
+the last beta, see README.beta.

+By default, this script builds the last stable release of opencomal,
+0.2.6, from December 2002. It's also possible to build the last beta,
+0.2.7-pre1-work, from January 2003. To do this, download the source from:
+
+http://www.josvisser.nl/opencomal/opencomal-0.2.7-pre1-work.tar.gz
+
+The md5sum is 43b90700cec264e8da4bd728b3e70cb1.
+
+Save the file in the same directory as opencomal.SlackBuild, then run
+the script with BETA=yes set in the environment. The resulting package
+will have a version number of 0.2.7pre1 (no hyphen or -work suffix).

+opencomal needed a lot of patching to get it building & running on modern
+Slackware. All these patches are by the SlackBuild author.
+
+01-missing_includes.diff
+  #include <string.h>
+
+02-vsprintf.diff
+  bizarre non-standards-compliant handling of vsprintf() causes immediate
+  segfault on startup, when it tries to print the banner.
+
+03-fix_auto_segfault.diff
+  missing NULL check, causes segfault in 'auto' mode when a syntax error
+  is entered, followed by ^C.
+
+04-mkdir.diff
+  fix the mkdir command so it actually reports errors.
+
+05-sys_errlist.diff
+  fix deprecation warning.
+
+06-noreturn.diff
+  squelch a bunch of spurious 'might be used uninitialized' warnings.
+  there are still a couple left, caveat emptor...

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.

+opencomal: opencomal (interpreter for Comal programming language)
+opencomal:
+opencomal: OpenComal is a portable and free implementation of the Comal
+opencomal: programming language written by Jos Visser. Currently supported
+opencomal: platforms are Unix, MsDos and Win32. Comal is a crossover between
+opencomal: Basic and Pascal, with the best features of both and none of the
+opencomal: drawbacks of either.
