              README file for the libxslt extensions
----------------------------------------------------------------------

These are XSLT extensions written in Python for use with the DocBook XML 
stylesheets and the libxslt library[1].

Currently, the only available extension is a function for adjusting column
widths in tables. For more information, see the section describing the 
equivalent Java extension in "DocBook XSL: The Complete Guide"[2].

----------------------------------------------------------------------
Preparations
----------------------------------------------------------------------
In addition to libxml2 and libxslt, the following software needs to 
be installed before you start using the extensions:

1. Python[3].

2. Python bindings for libxml2/libxslt. Most distributions of 
   libxml2/libxslt for Unix/Linux include these bindings.
   A native Windows port is provided by Stéphane Bidoul[4].

----------------------------------------------------------------------
Installation of the extensions
----------------------------------------------------------------------
No special installation step is needed.

----------------------------------------------------------------------
How to use the extensions
----------------------------------------------------------------------
Instead of using xsltproc, you run a Python program (xslt.py). The 
command has this general form:

python xslt.py xmlfile xslfile [outputfile] [param1=val1 [param2=val]...]

Modify paths, filenames, and parameters as needed. Make sure to set 
the "use.extensions" and "tablecolumns.extension" parameters to 1.
