Building CRaSH demos

CRaSH demos are built with Maven.

mvn package

it will produce:

• packaging/target/demo-kit-demos : the exploded directory
• packaging/target/demo-kit-demos.zip : the demos as zip

The default output directory is packaging/target, but you can override it using demo.output.directory property as following:

mvn package -Ddemo.output.directory="/home/foo/demos"

Install sublime text snippets

You can install some sublime text snippets to help you during the demo:

cd sublime-text
mvn install -Ddemo.sublimetext.directory="/path/to/sublime text"

Default OSX path is /Users/foo/Library/Application Support/Sublime Text 2/Packages/User
