Use:
    ant

...to compile the project.

Use:
    ant dist

...to generate the plugin jar file and a script to run scalac with the plugin.

Then, try for instance:
    ./scalac-funcheck -Xshow-phases

...and notice that funcheck runs right after refchecks. Note that
./scalac-funcheck is generated and contains the full path to the jar file, so
you can use it from any location and it will find what it needs. You may want
to symbolically link to it from ~/bin, for instance.

You can also try:
    ./scalac-funcheck -Xplugin-list

Try:
    ./scalac-funcheck Test.scala

...and notice that the plugin does something (in particular, the compilation
stops right after the plugin).

Try:
    ./scalac-funcheck -P:funcheck:with-code Test.scala

...to achieve the same result but with letting the compiler continue its work.

To clean up:
    ant clean

Useful for showing Scala AST
-----------------------------

Try:
   ./scalac-funcheck -Yshow-trees -Xprint:funcheck Test.scala

...to print the program's AST on the standard output

Try:
   ./scalac-funcheck -Ybrowse:funcheck Test.scala

...to print a Swing-based GUI for browsing the program's AST
