# This is a python script. You need a Python interpreter to run it.
# For example, ActiveState Python, which exists for windows.
# Changelog
+#
+# Based on ereader2html version 0.08 plus some later small fixes
+#
# 0.01 - Initial version
# 0.02 - Support more eReader files. Support bold text and links. Fix PML decoder parsing bug.
# 0.03 - Fix incorrect variable usage at one place.
# in some pdb files :-( due to the same id being used multiple times
# - Added correct charset encoding (pml is based on cp1252)
# - Added logging support.
-#
-# TODO run this through a profiler - speed increases so far was from
-# applying "quick known fixes", added (commented out) cprofiler call
# 0.05 - Improved type 272 support for sidebars, links, chapters, metainfo, etc
# 0.06 - Merge of 0.04 and 0.05. Improved HTML output
# Placed images in subfolder, so that it's possible to just
# conversion in this code.
# 0.07 - Further Improved type 272 support for sidebars with all earlier fixes
# 0.08 - fixed typos, removed extraneous things
-# 0.09 - tried to greatly improve html conversion especially with \t tags
+# 0.09 - fixed typos in first_pages to first_page to again support older formats
+# 0.10 - minor cleanups
+# 0.11 - fixups for using correct xml for footnotes and sidebars for use with Dropbook

# Changelog
-# 0.01 - Initial version
-# 0.02 - Support more eReader files. Support bold text and links. Fix PML decoder parsing bug.
-# 0.03 - Fix incorrect variable usage at one place.
-# 0.03b - enhancement by DeBockle (version 259 support)
-# Custom version 0.03 - no change to eReader support, only usability changes
-# - start of pep-8 indentation (spaces not tab), fix trailing blanks
-# - version variable, only one place to change
-# - added main routine, now callable as a library/module,
-# means tools can add optional support for ereader2html
-# - outdir is no longer a mandatory parameter (defaults based on input name if missing)
-# - time taken output to stdout
-# - Psyco support - reduces runtime by a factor of (over) 3!
-# E.g. (~600Kb file) 90 secs down to 24 secs
-# - newstyle classes
-# - changed map call to list comprehension
-# may not work with python 2.3
-# without Psyco this reduces runtime to 90%
-# E.g. 90 secs down to 77 secs
-# Psyco with map calls takes longer, do not run with map in Psyco JIT!
-# - izip calls used instead of zip (if available), further reduction
-# in run time (factor of 4.5).
-# E.g. (~600Kb file) 90 secs down to 20 secs
-# - Python 2.6+ support, avoid DeprecationWarning with sha/sha1
-# 0.04 - Footnote support, PML output, correct charset in html, support more PML tags
-# - Feature change, dump out PML file
-# - Added supprt for footnote tags. NOTE footnote ids appear to be bad (not usable)
-# in some pdb files :-( due to the same id being used multiple times
-# - Added correct charset encoding (pml is based on cp1252)
-# - Added logging support.
-#
-# TODO run this through a profiler - speed increases so far was from
-# applying "quick known fixes", added (commented out) cprofiler call
-# 0.05 - Improved type 272 support for sidebars, links, chapters, metainfo, etc
-# 0.06 - Merge of 0.04 and 0.05. Improved HTML output
-# Placed images in subfolder, so that it's possible to just
-# drop the book.pml file onto DropBook to make an unencrypted
-# copy of the eReader file.
-# Using that with Calibre works a lot better than the HTML
-# conversion in this code.
-# 0.07 - Further Improved type 272 support for sidebars with all earlier fixes
-# 0.08 - fixed typos, removed extraneous things
-# 0.09 - tried to greatly improve html conversion especially with \t tags

+# 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
