# Slackware build script for pcc (Portable C Compiler)
-# Written by Armin Besirovic <armin[at]linux[dot]org[dot]ba>
+
+# Originally written by Armin Besirovic <armin[at]linux[dot]org[dot]ba>
+
+# Modified by B. Watson <yalhcru@gmail.com>
+
+# 20141031 bkw:
+# - took over maintentance.
+# - upgraded for 1.1.0 beta series.
+# - combined pcc and pcc-libs into one build, since either one is
+# useless without the other.
+# - removed pcc-lib's 002-build-libpcc-with-pcc.patch as it's been
+# applied upstream in the 1.1.0 branch.
+# - use private /usr/libexec/pcc/ dir instead of installing stuff
+# directly in /usr/libexec. Probably just paranoia.
+# - rename cpp-pcc man page to pcpp, since the beta installs a
+# /usr/bin/pcpp.
+# - get rid of -j1 in make command, seems to no longer be needed.
+# - add logic to choose which compiler to use if CC not set.
+# - extract license from source, install to /usr/doc
+
+# notes:
+
+# - pcc 1.0 hasn't worked since Slackware 13.37. It builds & installs
+# fine, but anything compiled with it just segfaults in the
+# startup code. Hence the upgrade to a beta snapshot, which at
+# least can compile a working "hello world" on Slack 14.1.
+
+# - upstream only keeps about a weeks' worth of snapshot tarballs, so
+# so I'm self-hosting them. I do plan to update the snapshot version
+# from time to time, but *not* on a weekly basis. Eventually 1.1.0
+# will be released, and there will be much rejoicing.
+
+# - upstream filenames are pcc-1.1.0.BETA-<yyyymmdd>. If you want to
+# try a different snapshot, set VERSION=1.1.0_beta_<yyyymmdd> in
+# the env. AFAIK, the pcc and pcc-libs snapshot dates must always
+# match (this script enforces it).
