About Mr. Filter
================

Mr. Filter is an analog active filter design assistant.  It walks the user 
through the steps of designing a filter from the specification stage through
simulation.  The most recent information can be found at

https://sourceforge.net/project/screenshots.php?group_id=274571

and the code can be downloaded from

https://sourceforge.net/projects/mrfilter/files/

But as the project is in the pre-alpha stage, it's better to fetch the code
from mercurial:

hg clone http://mrfilter.hg.sourceforge.net:8000/hgroot/mrfilter/mrfilter mrfilter


Installation
============
Unix users can download the tarball, unpack it, then run

$ cd mrfilter-X.Y.Z (where X.Y.Z is the version number)
$ sudo python setup.py install

If you do not have superuser priveleges, you do a personal installation with
$ python setup.py install --home=~

That will put all the files in your home directory.  To use them you must set
these environment variables:
export PATH=~/bin:$PATH
export PYTHONPATH=~/lib/python:$PYTHONPATH

Windows is not yet officially supported, but should work with possibly minor
modification.


Requirements
============
mrfilter requires the following packages to be installed:
* scipy
* numpy (may be included with scipy)
* matplotlib
* gnucap and/or ngspice (for simulation)


Support
=======
For help with problems, or to submit patches, bugs, or feature requests, email
the mailing list: mrfilter-users@lists.sourceforge.net .  Bear in mind that
mrfilter is in an early stage of development.  Right now bugs are many,
features are lacking, and the project is changing rapidly.
