+# download_f2c
+#
+# Unpacks a directory full of f2c stuff obtained from netlib, naming
+# the directory f2c-YYYYMMDD (YYYYMMDD being the current date),
+# leaving it in current working directory.
+#
+# 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.)
