Is anyone familiar with tools that can be used to obscure source code so that it builds, but no longer contains comments or useful variable or procedure names?

If you can generate useful source code, you should be able to write a useful parser that strips out comments. You can also "search and replace" variable names w/ obscure ones - just dont miss any. ;) -r.w. On Tue, 28 Oct 1997, William H.

Do a search on ANDF -- not sure of the acronym's meaning anymore, but
I think there is a GNU version, so perhaps there is a working system
that can be had.
I think it's for architecturally independent distribution -- "compile"
or mangle your source with the ANDF system, and then finish the
compile (compile the garbled C code) on the target system.
(Odd thing for GNU to get involved in what with their source
availability theme.)
