+# This is also useful for making a copy of previous versions for parallel

# usage:
# perl pm2pl
# Run this from the perltidy main installation directory. It reads
-# bin/perltidy and lib/*.pm and writes a file 'perltidy' in the
+# bin/perltidy and lib/*.pm and writes a file 'perltidy-VERSION.pl' in the
# current directory.
-# Then, put the file 'perltidy' in your path and it should work (You
-# will also need to put the batch file 'perltidy.bat' in your path
-# under msdos/windows)
-
-# For unix systems, a sample Makefile is included as Makefile.npm
-
# This should work for a system with File::Spec,
# and for older Windows/Unix systems without File::Spec.
