• Set all the paths and change names of binaries
  (stupid. You would have to remember all names until you use some uniform naming method still you will keep guessing).
• Create many users and set different user paths
  (Foolish. Then changing version will be like logging as different user).
• Use a Customized Command Prompt
  (Elegant. Its like some developers are working)

How to Customize Command Prompt.

Well it involves 1,000 steps:-) no it doesn’t it involves 2 steps only.

1. Create a file Called YOURSYSTEM-VER-cofig.bat. Where YOURSYSTEM is the name of the system you are using and VER is the version of that specific system like python-2.6-config.bat.
2. Now put some codes in the file. Like:

@ECHO OFF
@SET PATH= %PATH%;C:\appand\your\path\here;D:\appand\one\more
@SET SOMEVARABLE=E:\some\path
@SET DIRCMD=/D /N
@PROMPT $G
@ECHO Setting environment for YOURSYSTEM VER
@ECHO %TIME% %DATE%
@ECHO Namaskar Criss.

3. Then create a new shortcut Right click on empty space or File -> New -> Shortcut.

I recommend you to keep all these files in one folder say with name config-all and with attribute as hidden.
