 The basic script assumes several things which may not be true for your install, things you should check for are:
 
 - The script assumes your GIT check directory is the slug of your WordPress plugin.  You can override this by editing the script and changing the "PLUGIN=" line to the correct slug.
-- The system command "mktemp" is used to store the temporary working copy of the plugin, you may want to change this if you have a busy system and don't want to look through a pile of temp directories to find the one you are looking for.
-- By default the following files are not commited to the SVN repo: README.md, CHANGES.md and the "bin" directory.  If you have other files you wish to exclude, edit the script and go down to the "# Remove special files" section and add them to the list of files to remove.
