=item _get_project($full_path)

A private routine returning a reference to the open project with the given name,
or else the empty string (when that project is not open)

full_path is a string identifying the project to be built and is of the form, 
e.g., "HD:ProjectFolder:MyProject.mcp".  It must be supplied.

=item build_project

Build a selected target of a project, saving any errors to a file, if supplied.
	
full_path is a string identifying the project to be built and is of the form, 
e.g., "HD:ProjectFolder:MyProject.mcp".  It must be supplied.

If target_name is the empty string, the current target of the selected project 
will be built, else, target_name should be a string matching a target name in 
the selected project.
	
If error_path is the empty string, errors will not be saved to a file,
else, error_path should be the full path of a file to save error messages into.

=item activate()

Launches CodeWarrior and brings it to the front.

Once found, path will be saved in ':idepath.txt' for future reference.
Edit or delete this file to change the location of the IDE.  If app is
moved, C<activate()> will prompt for a new location.

First looks for an open CodeWarrior app.  Second, tries to open previously
saved location in ':idepath.txt'.  Third, tries to find it and allow user
to choose it with Navigation Services (if present).  Fourth, uses good old
GUSI routines built-in to MacPerl for a Choose Directory dialog box.
