18# Takes a file (usually with a suffix of .plistsrc) and "compiles it" using
19# the gcc preprocessor.
20# The best way to use PlistCompiler is to add a custom build rule to your target
21# in Xcode with the following settings:
22# Process: "Source files with names matching:" "*.plistsrc"
23# using: "Custom script:"
24# "Path/to/PlistCompiler/relative/to/${SRCROOT}'
25# with output files:
26# ${BUILT_PRODUCTS_DIR}/${UNLOCALIZED_RESOURCES_FOLDER_PATH}/${INPUT_FILE_BASE}.plist
27# You can control the include paths by setting the 
28# GTM_PLIST_COMPILER_INCLUDE_PATHS environment variable to a colon delimited
29# path string. It defaults to "."
