# Tests Boost Jam & Boost Build's source & target file name handling. Originally
# added as a regression test for a bug causing versions included in the Boost
# library 1.35 release (and earlier) not handling Windows short file names
# correctly. Also tests handling target file names containing spaces.
# Implementation notes:
#
# We expect Boost Jam to automatically update the 'all' target when no target
# has been explicitly specified on the command line.
#
# Windows short & long file names can not be matched until the file in
# question actually exists so we need to create the file before running Boost
# Jam.
#
# Currently Windows short file names are hardcoded but in case this proves
# insufficient we should use the GetShortPathName() Windows API to get the
# correct short file for a given long file name.
