Usage
=====
2013-07-31 18:51:01 +00:00
|project_name| consists of a number of commands. Each command accepts
a number of arguments and options. The following sections will describe each
command in detail.
Quiet by default
----------------
Like most UNIX commands |project_name| is quiet by default but the ``-v`` or
``--verbose`` option can be used to get the program to output more status
messages as it is processing.
