+# Empty (or only whitespace) input lines are ignored.
+# Lines beginning with # are ignored.
+# Lines with just one word are ignored.
+# Otherwise, the line has two or more whitespace-separated words:
+#   the first word is the source, the second word is the destination,
+#   other optional words are options.
+# The possible options are "gpl" (to replace the license with the GPL)
+#   and "doclicense" (to replace @include doclicense.texi with fdl.texi).
+#   Unrecognized options are ignored.
+# $VARIABLE expansions are done (with sh eval).
+# 
+# This script is used in gnulib and texinfo; the input files are named
