+# Wed Dec 23 13:27:50 1992: Rik Faith (faith@cs.unc.edu) applied changes
+# based on Mitchum DSouza (mitchum.dsouza@mrc-apu.cam.ac.uk) cat patches.
+# Also, cleaned up code and make it work with NET-2 doc pages.
+#
+# makewhatis-1.4: aeb 940802, 941007, 950417
+# Fixed so that the -c option works correctly for the cat pages
+# on my machine. Fix for -u by Nan Zou (nan@ksu.ksu.edu).
+# Many minor changes.
+# The -s option is undocumented, and may well disappear again.
+#
+# Sat Mar 23 1996: Michael Hamilton (michael@actrix.gen.nz).
+# I changed the script to invoke gawk only once for each directory tree.
+# This speeds things up considerably (from 30 minutes down to 1.5 minutes
+# on my 486DX66).
+# 960401 - aeb: slight adaptation to work correctly with cat pages.
+# 960510 - added fixes by brennan@raven.ca.boeing.com, author of mawk.
+# 971012 - replaced "test -z" - it doesnt work on SunOS 4.1.3_U1.
+# 980710 - be more careful with TMPFILE.
+# 000323 - do not change PATH, better treatment of catpages - Bryan Henderson.
+# 011117 - avoid suspicious filenames.
+# 030310 - find files only; fix LAPACK cruft; no /usr/man default;
+# use /dev/stderr instead of /dev/tty; handle files with strange names;
+# add support for chinese, hungarian, indonesian, japanese, korean,
+# polish, russian (Thierry Vignaud).
+#
+# makewhatis 1.6: Federico Lucifredi
