Figured out how to run the Scala REPL under Cygwin/tmux in Windows.md

Scala REPL on Cygwin

# Getting the Scala REPL to work on Cygwin

There are some [nuances](https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&cad=rja&uact=8&sqi=2&ved=0CCQQFjAB&url=https%3A%2F%2Fwww.java.net%2Fblog%2Fcayhorstmann%2Farchive%2F2010%2F11%2F24%2Freport-sewer-hole-cygwin-jline-rxvt-and-scala-repl&ei=JKh0VLfQBISkyQSi_4CgDg&usg=AFQjCNEnrpRtLU8SZGXW9K11_KTPfBkzWA&sig2=0FHjPkgXNe0h9abfwZNo0w) to getting the Scala REPL working in Cygwin.

If you install version 2.11.4 for Windows, `/Applications32/scala/bin/scala` already attempts to follow these instructions.  If you're running under MinGW with `TERM=xterm-256color`, it works.  However when you start tmux or screen, it often changes the value of `TERM`.  You can get around this by:

    TERM=xterm-256color /Applications32/scala/bin/scala

It may be more convenient to drop this in a script, such as `$HOME/bin/scala`

```
#!/bin/bash

#Set TERM so that scala's script realizes we're in a cygwin environment, even under tmux (Which sets TERM to `screen`).
TERM=xterm-256color; SCALA_RUNNER_DEBUG=true /Applications32/scala/bin/scala
```
