# Duke Nukem 3D High Resolution Pack Extractor  v0.7.3  2015-02-03
#
# Author: LeoD
# License: ISC license : http://opensource.org/licenses/isc-license.txt
#
# This script extracts a working copy of your local Duke Nukem 3D High
# Resolution Pack's Subversion repository, ready for zipping and distribution.
# This is mostly done by hierarchically parsing the *.def files.
# PolyMER or PolyMOST only versions can be chosen.
# On Windows you might want MSYS' zip to create package files.
# ("mingw-get install msys-zip")
# MinGW/MSYS performance is horrible, better go Linux. Even my virtual Debian
# machine accessing the Windows drive is 5 to 10 times faster.
# But it still sucks. This needs to become a Perl script one day.
# Or maybe MSYS' bash gets finally updated to 4.* and I'll use its regex engine.
