I read this: pp only to create executable when source has changed

Update: Perhaps this helps:

Makefile

hello: hello.pl Foo.pm
    pp hello.pl -o hello.exe
[download]

Foo.pm

package Foo;
# test1
1;
[download]

hello.pl

#!/c:/perl/bin/perl
use lib q(.);
use Foo;
print "Hello!\n";
[download]

First call of dmake builds hello.exe. Next call shows `hello' is up to date. Change Foo.pm and run dmake.

Update: Another weird use of make ;-) 28.13 make Isn't Just for Programmers! in "Unix Power Tools"

OK, i've bought the book and i hope Tim doesn't blame...

manual: ch01.fmt ch02.fmt ch03.fmt
        lp ch0[1-3].fmt
ch01.fmt: ch01
        nroff -mm ch01 > ch01.fmt
ch02.fmt: ch02
        tbl ch02 | nroff -mm > ch02.fmt
ch03.fmt: ch03a ch03b ch03c
        nroff -mm ch03[abc] > ch03.fmt
