+minimal-basic (compiler for ECMA-55 Minimal BASIC)
+
+This software is a compiler for 'Minimal BASIC' as specified by the
+ECMA-55 standard. The target is AMD64/EM64T/x86-64 machines running a
+modern Linux distribution.
+
+The compiler is called ecma55, but it's normally called via wrapper
+scripts called BASICC, BASICCS, or BASICCW. Man pages are included for
+all of these commands.
+
+There's sample code in /usr/share/minimal-basic, and quite a bit
+of documentation in /usr/doc/minimal-basic-$VERSION, including a
+copy of the language standard (ECMA-55.TXT) and a complete book
+(Learn_BASIC.pdf).
+
+Note: This will only compile on x86_64 because it's partly written in
+x86_64 assembly. No way will it ever compile for 32-bit x86 (or any
+ARM). Even if it would build on 32-bit, it would be a cross compiler:
+it only generates x86_64 code, which would not be very useful on an
+x86 system.

+# Abandon all hope, ye who attempt to build this on non-x86_64
+# platforms. The ecma55 binary gets linked with a bunch of x86_64
+# object files in a directory named AMD64 (which ought to be a clue),
+# which are built from x86_64 assembly source (not C). Nothing you do
+# (hacking up the Makefile, etc) will let you link x86_64 objects with
+# non-x86_64 ones. Seriously. Do not email me asking for help with it.
+
+# Building on multilib should be possible, but I haven't tested it.
+# If you do, you can only build an x86_64 binary. See above.
+
+# There's a Makefile.clang, but it won't work on Slackware 15.0's
+# clang 13.x because it's too *new*. That's a rare situation in
+# Slackware...
+
+# There's also a Makefile.tcc, which actually does work with the
+# tcc in our repo (20220221_308d8d1), but I see no advantage to
+# building with tcc. And no, using tcc won't get around the "only
