This is a simple helper function to automatically titlecase chapter headings, etc throughout a Standard Ebooks project. It looks for both <h1>, <h2> etc as well as attributes such as epub:type="title" or "subtitle". It is written in Python.
Usage: titlecaser DIRECTORY
Note that it shells out to se titlecase to do the actual titlecasing, so installation of the SE tools is an essential requirement.
The function correctly handles headings which include tags such as <abbr> or semanticated italics such as <i epub:type="se:name.publication.book">.
The function ignores Standard Ebooks template files such as uncopyright.xhtml, toc.xhtml, etc.
