+# convert_to_f2c [g2c-dir]
+#
+# Renames certain files in a g2c (libg2c) directory so they no longer have the
+# `.netlib' suffix, a la netlib's f2c distribution.  If `g2c-dir' is not
+# specified, `g2c-YYYYMMDD' is the default, where YYYYMMDD is the current
+# date.  The directory is renamed such that the first `g' becomes an `f',
+# usually `g2c-YYYYMMDD' -> `f2c-YYYYMMDD'.

+#
+# This shell script downloads the tarball from netlib, unpacks everything,
+# and strips off the redundant files, leaving a bare-bones (but fully
+# reproducible) f2c source directory.  (You must have yacc/bison to rebuild
+# gram.c, by the way.)
