#
# Purpose: Syncs, builds and runs tests on the steam code in
#          the currently active p4 clientspec
#
#=============================================================================

# INSTALLATION INSTRUCTIONS:
#
# 1. add the vc compiler solution compiler devenv.exe to the path (defaults to being in "C:\\Program Files\\Microsoft Visual Studio .NET 2003\\Common7\\IDE\\devenv.exe")
# 2. create a P4 clientspec that contains the steam code, eg. //steam/main/...
# 3. make that the default clientspec
# 4. sync to it
# 5. run this build script from inside that directory
