Prerequisites

The following software needs to be installed in order to set up configuration versioning.

Xoom client installation, which includes the versioning script and other required Xoom tools and libraries.
Windows PowerShell v2.0 or later. The installation can be downloaded for all current Windows systems, including Windows Server 2003 or Windows Server 2008 x64.
Note:
When first using Powershell, you must set the Execution Policy to Remote Signed in order to be able to run the script:
```
PS> Set-ExecutionPolicy RemoteSigned
```
This enables the running of unsigned local scripts, while keeping the requirement on remote scripts to be signed. Find more details here.
A supported revision control system. Xoom currently supports Git, Mercurial and Subversion. Please contact us if you wish to use a revision control system that is not supported at this time.

The command line tools for the chosen revision control system need to be installed for the versioning script to work. This is not the default configuration with some systems (e.g. TortoiseSvn), so choose your installation options carefully. The system also needs to be configured for successful use of revision control system's commands. For example, authentication information and/or certificates need to be in place, and the location of the relevant commands need to be on the system PATH. Consult the relevant revision control system documentation if necessary.
