CVSWrapper

The CVSWrapper will assist you to keep track of the different versions of your scripts as you develop your scripts.
It supports both SVN and CVS repositories and gives you an option which default type repository to use.

Installation instructions.

Functions.

F12 will update the CVS repository.

These steps are performed:

The First time this script runs it will show a Menu where you choose the versioning system you want to use for the default repository. This default repository is used when the source file directory isn't using a versioning system yet. I prefer using SVN because its faster and has more capabilities but both SVN and CVS will work and you only need one to be able to work with this program. You can also change the Directory in which to create the svnRepository -or- cvsRepository and the svnAutoIt3Scripts -or- cvsAutoIt3Scripts directories. AFter you Click the "Use SVN" or "Use CVS", the CVS commands will be performed to initialize the repository.
Check if a SVN/CVS is already defined for the current script:
- In case a SVN/CVS is already defined it will update the script in the current SVN/CVS repository.
- Else it will copy the current version of your script into a subdirectory of CVSWrapper called: svn/cvsAutoIt3Scripts
  and Run the CVS program to add the updated version to the repository stored in directory: svn/cvsRepository

Alt+F12 show the difference between the current edited version and the last save version.

In case a CVS is already defined it will retrieve the last saved version from the SVN/CVS repository into a temp file and start WinMerge.
Else it will start WinMerge comparing it with the version in the subdirectory of CVSWrapper called: cvsAutoIt3Scripts.

Just keep clicking

to go to the next difference between the CVS and the working copy of the script.

Ctrl+F12 will open the Windows Explorer to allow you to perform CVS tasks.

Tasks like: Remove/History/Special Update/Annotate.
This can be done by doing a Right-Mouse-click on the Script, Select CVS and then selecting the desired option.
