"""Make a symlink and optionally touch a file (to handle dependencies).

Usage:
|
|
symlink.py [options] sources... target
|
|
|
|
A sym link to source is created at target. If multiple sources are specfied,
|
|
then target is assumed to be a directory, and will contain all the links to
|
|
the sources (basenames identical to their source).
