# 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.)
