"""
Phony compiler for testing SCons.
Copies its source files to the target file, dropping lines that match
a pattern, so we can recognize the tool has made a modification.
Intended for use as a *COM construction variable.
Calling convention is:
argv[1] the function of the script (cc, c++, as, link etc.)
argv[2] the output file to write
argv[3:] one or more input files to "compile"
Invocation often looks like:
Environment(CCCOM = r'%(_python_)s mycompile.py cc $TARGET $SOURCE', ...
