# xPml2XHtml.py
#
# This is a python script. You need a Python interpreter to run it.
# For example, ActiveState Python, which exists for windows.
#
# Based on Code, Input and Ideas from:
# The Dark Reverser (original author)
# Kevin Hendricks
# Logan Kennelly
# John Schember (Calibre project)
# WayneD's (perl pml2html.pl)
# Changelog
# 0.02 - tried to greatly improve html conversion especially with \t tags
# 0.03 - more cleanup, a few fixes, and add in use of tidy to output xhtml
# 0.04 - incorporate more cleanups
# 0.05 - add check to fix block elements nested in inline elements which are not allowed
# 0.07 - handle clean up for remains left over from fixing nesting issues rampant in pml
# 0.08 - deal with inline style tags nesting issues in new way using a style tag list
# 0.09 - add in support for wrapping all text not in a block in <p></p> tags
# 0.10 - treat links effectively as block elements for style markup
# 0.11 - add in various paragraphs indentations to handle leading spaces that html would ignore or compress
# 0.12 - add in support for handling xml based pml footnotes and sidebars - using pseudo pml tags
# 0.14 - add in full header info parsing and remove need for bookinfo.txt
# 0.15 - cleanup high chars better handled, optional use of tidy with command line switch
# 0.16 - use proper and safe temporary file when passing things to tidy
# 0.17 - add support for tidy.exe under windows
# 0.18 - fix corner case of lines that start with \axxx or \Uxxxx tags
# 0.19 - change to use auto flushed stdout, and use proper return values
# 0.20 - properly handle T markup inside links
# 0.21 - properly handle new sigil Chapter Breaks for 0.2X series and up
