+#
+# @(#) mk2knr.pl - generates a perl script that converts lexemes to K&R-style
+#
+# How to use this script:
+# - In the busybox directory type 'scripts/mk2knr.pl files-you-want-to-convert'
+# - Review the 'convertme.pl' script generated and remove / edit any of the
+# substitutions in there (please especially check for false positives)
+# - Type './convertme.pl same-files-as-before'
+# - Compile and see if it works
+#
+# BUGS: This script does not ignore strings inside comments or strings inside
+# quotes (it probably should).
+
+# set this to something else if you want
+$convertme = 'convertme.pl';
+
+# internal-use variables (don't touch)
+$convert = 0;
