+obcpl (BCPL compiler)
+
+This is an x86 (IA-32) port of the "classic" old BCPL compiler (around
+1980) from the Tripos Research Group at Cambridge University.
+
+As a real, working computer language implementation, that can be studied,
+modified, and played with, this old BCPL compiler has a good deal to
+recommend it. The compiler frontend consists of only about 2000 lines
+of BCPL code, and (as supplied here) compiles to a static (fully-linked)
+x86 binary that is less than 36000 bytes in size.
+
+x86_64 note: obcpl doesn't require multilib on Slackware64. It only
+generates 32-bit x86 code, but the binaries it creates are 100% statically
+linked, and will run fine on Slackware64 without multlib.

+# 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.
