lyx2lyx is now a frontend to the LyX module.
The code in LyX was refactorized and now we have two different classes that derive from a base class. One for new files and the other for existing files. New class for paragraphs. New code to return the toc of a file. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@9092 a592a061-630c-0410-9148-cb99ea01b6c8

* lyx2lyx: moved code to LyX module making effectively lyx2lyx and
|
||||
interface to the LyX module.
|
||||
|
||||
* LyX.py: white space changes. New class that serves as the basis
|
||||
to two derived classes. One for reading and another for new files.
|
||||
New function get_toc, to be used in Doc_toc.py in the
|
||||
documentation directory.
|
||||
New class paragraph, to read paragraphs from the lyx file.
