== Gotchas ==
== Basic ==
 
* cvs2svn is known to break binary files (images) which were not imported into the CVS with the -kb flag. Luckily Glynn fixed most of these some months ago.
 
* Files using keyword substitution, such as $Date$ in the description.html files, will have to have support for that enabled manually, once per file (or write a find routine with | xargs svn ...).
$ svn propset svn:keywords "Date" filename.txt
$ svn commit
or
$ find . -name '*.c' | xargs svn propset svn:keywords "Date"
$ find . -name '*.html' | xargs svn propset svn:keywords "Date"
$ svn commit


* how to maintain timestamps of files? We want to keep the last modification date, not the date of local download
* The SVN command line interface is just like CVS, many tasks are identical - just change the program name from cvs to svn.

GRASS OSGeo SVN repository structure

See Discussion page for details. 

/grass-svn

|    |
|    +---/trunk (grass6 CVS HEAD)
|    |
|    +---/branches
