I created a bash script that will allow Sencha SDK Tools to co-exist with Sencha Cmd on the same system. The script has been tested only on Mac OS X but I think it works pretty good. Once the script has been run, instead of using the 'sencha' command for the SDK Tools, you use 'sencha-legacy'. The 'sencha' command from Sencha Cmd takes precedence and is not modified.
The script is as less intrusive as possible as it does not modify either framework, rather it makes some modifications to the .bash_profile and .bashrc profile scripts as well as creating a couple of symlinks. Feedback is appreciated.
As with my other projects, I'll be publishing supporting material this week.
