I guessed about this. But I still need a full list of supported tool.
mk/replace.mk? What if I write
USE_TOOLS += gm4?
Will it work under NetBSD (where it external and is named gm4)
and under Linux (GNU version in most distributions)?
Is it possible to tell "I need POSIX compatible <program>".
On some systems, for example, awk == oawk.

Ok.

There is no pkgsrc package for bzlib.
What I should include to Makefile?
