# Try a DJGPP installation using pakke. This assumes that you have a mirror
# of the DJGPP archive available and specified in the 'share/pakke/pakkerc'
# file in you DJGPP directory. The base directory of the the DJGPP archive
# should be given as a command-line argument.
#
# Example:
#
#     <this-script> z:/djgpp-mirror
#
# When prompted whether to overwrite DSMs on installation of djgpp-dsms,
# choose to skip overwriting the already installed files. The DSMs from
# pakke's sources are likely to have bugfixes over the ones in the packages
# on Simtel.NET.
