/** Version Control for LyX.
|
|
This is the class giving the verison control features to LyX. It is
|
|
intended to support different kinds of version control, but at this point
|
|
we will only support RCS. Later CVS is a likely candidate for support.
|
|
The support in LyX is based loosely upon the version control in GNU Emacs,
|
|
but is not as extensive as that one. See examples/VC.lyx for a simple
|
|
tutorial and manual for the use of the version control system in LyX.
|
|
|
|
LyXVC use this algorithm when it searches for VC files:
|
|
for RCS it searches for <filename>,v and RCS/<filename>,v similar
|
|
should be done for CVS. By doing this there doesn't need to be any
|
|
special support for VC in the lyx format, and this is especially good
|
|
when the lyx format will be a subset of LaTeX.
