# mk(1)

mk is a build automation tool.

A mkfile is a script that mk can read to derive files from other files. 

When given a target, mk reads the rule for the target and calculates a
graph of dependencies.  mk then derives all targets and dependencies
with the recipes given.

All targets and dependencies are assumed to be files, unless the rule
is marked virtual.
