decomment - remove comments from C and C++ files
decomment processes the named files, or standard input if none are
named, copying their contents to standard output with comments removed.
Line numbers in the input file(s) and out file(s) are unchanged, that
is, if main() occurs on line 40 in the input, it will also appear on
line 40 in the output despite comment removal.
decomment may be used to remove comments in order to simply other
programs which process source code.
No parsing-related diagnostics.
