Dancer-Bootstrap-FontAwesome-Template name changer.

Usage: $(basename $0) [NEW-NAME]

This program will replace the hard-coded 'dancer_bootstrap_fontawesome_template'
with NEW-NAME in all the right places.

NOTE: This can't be undone, and you can't change the name again automatically.

If you want to change it again, do so manually:
  1. In 'config.xml':
      Set 'appname' to NEWNAME
  2. In directory 'lib':
      Rename 'OLDNAME.pm' to 'NEWNAME.pm'
  3. In 'bin/app/pl':
      Change 'use OLDNAME.pm' to 'use NEWNAME.pm'
  4. In 'Makefile.PL':
      Change OLDNAME to NEWNAME.
