====== Subversion Tips & Tricks ======
===== Ignore .pyc files in Subversion =====
Create a file (.svnignore) with the regular expressions
*.pyc
*~
Run svn propset on the project
   svn -R propset svn:ignore -F .svnignore .
   * **-R** indicates that you are doing this recursively so all the directories ignore these.
   * **-F** indicates the file we just created with the regular expressions.
If you’ve already got yourself into the mess of versioning your compiled files, then you might want to do a few things.
   * Revert all the .pyc files (you can always recompile them). You don’t want there to be any local changes when you try to delete them:
   find -name "*.pyc" -exec svn revert {} \;
   * Delete all the .pyc files using `svn delete`:
   find -name "*.pyc" -exec svn delete {} \;
   * Finally recompile and re-run the svn ignore code above
===== Adding external SVN repo into yours =====
mkdir external
svn pe svn:externals external
add local and remote dir (as for example)
