#
# This is a python script. You need a Python interpreter to run it.
# For example, ActiveState Python, which exists for windows.
# 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

#
# This is a python script. You need a Python interpreter to run it.
# For example, ActiveState Python, which exists for windows.
# 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
