Introduction: what is pss?
You can think of pss as an enhanced grep designed to search inside source code files. pss is very similar to the Perl ack tool (see https://bitbucket.org/eliben/pss/wiki/PssAndAck).
pss needs only Python to run. It works with with Python versions 2.6, 2.7 and 3.2 on Linux and Windows (though I don't see a reason it shouldn't work on other platforms as well).
When you unzip the source distribution, run:
> python setup.py install
Alternatively, pss can be installed from PyPi (Python package index):
> pip install pss
How to use it?
pss is meant to be executed from the command line. Running it with no arguments or with -h will print a detailed usage message.
For some detailed usage examples, check out the Usage wiki page - https://bitbucket.org/eliben/pss/wiki/Usage.
pss is open-source software. Its code is in the public domain. See the LICENSE file for more details.
