"""
NewSvnProject creates a new Subversion repository, imports new files to it, then
checks out those files back to original directory, with a single command or
drag'n'drop.
Instructions
============
* Save source code as NewSvnProject.py
* Modify globals below for your system. [one-time]
SVN_EXE
SVN_ADMIN_EXE
REPO_DIR
REPO_URL
* Call from command line:
Example: C:\Python24\python.exe C:\Dev\PyUtils\src\NewSvnProject.py C:\Dev\C++\A2Work
* Or setup a drag'n'drop shortcut according to your system.
Notes
=====
* Backup your work before trying this.
* Close applications accessing folder or files in project.
* Windows: Don't have project folder open in right Explorer pane.
* Original work files and old repositories are protected from loss by renaming
directories with a timestamp.
* Developed and tested under Windows, but does not use Windows calls, so it
should work from command lines on Unix and Macs. Let me know.
* Deletes old .svn dirs in project, if present.
