#   MinGW cross compiling environment  (pre-1.1)
#   =================================
#
#   http://www.profv.de/mingw_cross_env/
#
#   This script compiles a MinGW cross compiler and cross compiles
#   many free libraries such as GD and SDL. Thus, it provides you
#   a nice MinGW cross compiling environment. All necessary source
#   packages are downloaded automatically.
#
#
#   Usage:  ./build_mingw_cross_env.sh  [ action ]
#
#   <no action>
#       same as '--download', followed by '--build'.
#
#   --new-versions
#       retrieve the new version numbers of all packages
#       (modifies the script in-place, use with caution!)
#
#   --download
#       download all packages in download/
#       (resumes incomplete downloads)
#
#   --build
#       build the packages in src/ and usr/, create mingw_cross_env.tar.gz
#       (needs a prepared download/ directory
#        or a previous '--download' run)
#
#   --build-experimental
#       build the experimental packages
#       (allows fast testing of new additions to the script,
#        needs a prepared mingw_cross_env.tar.gz archive
#        or a previous '--build' run)
