 *    File:    mac_genprops.cpp
 *    Mac Codewarrior plugin version of genprops.
 *    Because of the different natures of the commandline genprops and a CodeWarrior plugin compiler,
 *    uprops.dat will be generated multiple times (how many times depends on the number of files
 *    being processed by the compiler). This is because genprops has hardcoded the processing of each
 *    file when it is run but the compiler wrapper of genprops calls genprops for each individual
 *    file. Therefore, as each file is 'compiled', all of the files are processed by genprops. The 
 *    final output isn't affected (since a new file will replace the old one), only the efficiency 
 *    by which the files are processed. This extra time isn't noticable with only a few files. One 
 *    workaround to this problem would be to only include one of the files in the project target. 
 *    The downside of this approach is that the other files being processed wouldn't be directly 
 *    accessable from the project window and it would appear to the user that only one file was 
 *    being processed when in fact multiple files were used to produce uprops.dat.
