This directory contains the modules for Markup-0.2.10
compatibility. The modules consist mainly of wrapper classes for the
new PXP classes, and translate the old methods to the new ones.

Please note that the compatibility is not perfect. Sometimes there are
new methods which do not exist in Markup-0.2.10, and sometimes even
existing methods changed their signature. I have tried to avoid that,
but there are some ugly cases which are hard to solve without such
modifications. 

Translating old methods into new methods costs time and
memory. Because of this, it is best to consider the compatibility
modules as migration path to PXP: You can test whether PXP parses your
input files, and you can compare the old API with the new API
directly. (However, it is hard to test new features of PXP with the
compatibility modules; the old API does not reflect the new features.)

The compatibility modules are currently maintained, but that will stop
once PXP has been established.
