# This is a hack for generating a Microsoft Developer Studio project and
# workspace files (.dsp/.dsw) for building Coin from the MSVC++ IDE.  It
# hooks into the Automake process as a fake compiler, building the project
# file instead of the sources.
#
# TODO:
#  - Defines should be verified:
#     are WIN32 and _WINDOWS necessary?
#     should _DEBUG be defined?
#  - Wtf is "Package Owner <4>"?  Want this to mean SIM if possible :),
#    not MS if <4> is some code for that...
#  - Indicate that the dsp file is *not* generated by Microsoft Developer
#    Studio?  Will the MSVC++ IDE eat "foreign" dsp files?
#  - Ensure that thammer and preng put me in their wills...

# NOTES
# * The large blocks of text were originally written as "cat >file <<EOF"
#   blocks, but for some reason I still don't understand, that did not
#   produce any input to file in the case of SoWin on Cygwin.  It worked
#   for other cases.  It therefore had to be obfuscated into large
#   echo "" >file blocks so it would work universally for all the projects.
