SYNOPSIS
$0 [OPTIONS] <files>
OPTIONS
--help, -h show this help
--short, -s short graph with no external dependencies
<files> list of zero or more configure.ac files
(default: ${files})
DESCRIPTION
Evaluates dependencies of all the given configure.ac file. By
default takes the local configure.ac. Outputs a graphwiz dot file
with the dependencies. Solid lines are required dependencies, dotted
lines are optional dependencies.
EXAMPLE
Evaluate all dependencies between all local subversion and git
projects, if they are in the path ~/svn and ~/git:
$0 ~/svn/*/configure.ac ~/git/*/configure.ac
