@@ -4,6 +4,19 @@ Munt is a multi-platform software synthesizer emulating (somewhat
 inaccurately) pre-GM MIDI devices such as the Roland MT-32, CM-32L,
 CM-64 and LAPC-1.
 
-ROMS for these devices are not included.
+A few ROMS for these devices are included: the v1.07 ROM for the MT-32
+and the v1.02 ROM for the CM-32L. The applications have been patched
+to use the packaged ROMs by default, though you can use other ROMs
+easily enough.
 
-This will install both the desktop application and the shared library.
+This will install the desktop applications (mt32emu-qt and xmt32), the
+command-line tools (mt32emu-smf2wav and mt32d), the shared library,
+and the headers.
+
+Optional dependency: jack (autodetected). If jack is present,
+munt will be built with support for it. If this package is built
+with jack, it uses POSIX filesystem capabilities to execute with
+elevated privileges (required for realtime audio processing). This
+may be considered a security/stability risk. Please read
+http://www.slackbuilds.org/caps/ for more information. To disable
+capabilities, pass SETCAP=no to the script.

+/* interleave.c - B. Watson, April 2023, WTFPL licensed.
+
+   Given two files of the same size, creates a 3rd file whose contents are:
+
+   file 1, byte 1
+   file 2, byte 1
+   file 1, byte 2
+   file 2, byte 2
+   file 1, byte 3
+   file 2, byte 3
+   ...etc.
+
+   If file1 contains "foo" and file2 contains "bar", the output will
+   be "fboaor". The output is always twice the size of one of the
+   input files (or, the same size as both input files combined).
+
+   Output file is silently overwritten if it already exists.
+
+   Exit status is 0 for success, non-zero for failure, with a hopefully
+   useful error message.
+
+   Compile me with:
+     gcc -Wall -O2 -o interleave interleave.c
+
+   This could be done more efficiently and without an artificial file
+   size limit, but the current implementation reads everything into a
+   statically sized buffer for simpliticy.
