Warpin is a special tool developed by the people of Netlabs that allows you to install and de-install programs in an easy way. This is the Odin version you can use to activate the debug options to generate debug logs. These logs can be used by the developers to track down bugs in the Odin code. The fact that this is a debug version does not imply that large debug logs are written to your hard disk. In the early days this was indeed the case, but now the debug options are standard deactivated and must be activated explicitly by adding an environment variable.
Installation is very straightforward.
It is not necessary to make modifications to your config.sys. For a further explanation of the installation we assume that you'll be using the normal release version of Odin. If you want it you can also do this in another partition, but I don't recommend this. This is not because it will cause problems for ODIN, but because a lot of Windows programs assume that the system directories are situated on the C partition and therefore try to copy and configure all kinds of files to the C-partition. This registers WarpIN with os2.ini and creates a folder that contains the program objects.
