:: -- What is Raven?
:: A DOS Batch wrapper around mvn to save output to file and open it in an editor

:: ------------------------------------------------------------------------------
:: Set-up Dependencies first.
:: - This script
::    - Save this script as raven.bat in some folder you like to use for utilities etc.
::    - Add the path (folder/directory name) where this script lives to your PATH (*see note 1*).
::    - Otherwise you will have to use the absolute path to this script: e.g. "C:\myApps\Batch\raven" instead of just "raven".
:: - Maven
::    - Download it from: http://maven.apache.org/
::    - Set M2_HOME variable (*see note 1*) or LOCAL_M2_HOME in this script.
:: - Java
::    - Download and install it from: http://www.oracle.com/technetwork/java/javase/downloads/index.html
::    - Set JAVA_HOME variable (*see note 1*) or LOCAL_JAVA_HOME in this script.
:: - mtee.exe (to send output to file and console)
::    - Download mtee.exe from http://www.commandline.co.uk/mtee/
::    - Add the path (folder/directory name) where mtee.exe lives to your PATH (*see note 1*) or set MTEE variable in this script.
:: - Your favourite text editor.
::    - This script defaults to notepad. If you like it, do nothing.
::    - If you want to use something else, set EDITOR in this script
:: - Temp dir
::    - This script defaults to %TEMP%\maven.
::    - If you want to use something else, set TMPDIR in this script

:: How to use this script.
:: - Instead of using "mvn", just use "raven", e.g.
::       raven clean deploy
::       C:\myApps\Batch\raven clean deploy

:: Note 1 - changing PATH or other environment variables on Win7 and above: two options.
:: - OPTION 1: Start button > Search for "Environment Variables for your account" > modify PATH (or other variable) in top section, "user variables for USERNAME"
::    - No re-boot required, just restart the DOS prompt.
::    - PATH is set only for your user. Other logged users will not see it.
:: - OPTION 2: Start button > Search for "Edit the System Environment Variables" > Environment Variables > modify PATH (or other variable) in bottom section, "System Variables"
::    - Re-boot required.
::    - PATH is set for all logged in users.

:: History
:: Wednesday 07 January 2015, 07:07:33 PM
:: - Updated to check java, maven, mtee temp dir and editor variables.
:: Thursday 08 January 2015, 04:57:36 PM
:: - Modified the way this script looks for maven and java such that it always uses local versions first.
