You must have python 1.5b1 or newer to run PyLR, as it works with the builtin package support of that version. To build: 1) decide whether you want the PyLRengine module to be a shared library. If not, comment out the '*shared*' line in Setup. 2)type make -f Makefile boot; make that should build the package. To install: If you want to install PyLR in your python distribution, just copy over the PyLR directory to your site-packages directory. If you want to save a little space, take a look at the __init__ file doc string in the top directory and it shows the necessary files (distribution minus Makefile, sedscript, etc). Also, there is a script (pgen.py) you may want in /usr/local/bin or something more accessible as executable from your shell. There is html documentation in the doc/ directory. To test: pgen.py PyLR/tstpspec tst diff tst PyLR/Parsers/gram.py the only difference should be the date line.
