:) carefully, there. i'm only looking for a [tng]roff tutorial so
that I can start sending patches for the man page. :)
aside: not to insult anyone or anything like that, plus I'm aware
make is not a programming language interpreter, but it's really
braindamaged. consider this:
.for FOO in foo bar baz
FOO=${FOO}
.if !empty(FOO:S/baz//)
BAR+= ${FOO}
.endif
.endfor
all:
@echo BAR: ${BAR}
comment out the second line to break it.
