[jbosstools-dev] Question on ASTools profiling

[Max Rydahl Andersen]

Thanks Martes - I don't think this was what Rob referred to *but* its interesting
to see such writeup on how to get started from a new comer.

Reading your write up reminds me we could benefit from a doc that focus on the first steps instead of having
too many details upfront.

Instead of putting it on a mojo which very few can access could you submit a PR 
to fix/improve https://github.com/jbosstools/jbosstools-devdoc/blob/master/building/how_to_build_jbosstools_4.adoc
or simply add a new document at https://github.com/jbosstools/jbosstools-devdoc/tree/master/building ?

However, you will probably need to read any README.md that exists as a wiki howto.
