/**
 * Checks out files from a specific StarTeam server, project, view, and
 * folder.
 * <BR><BR>
 * This program logs in to a StarTeam server and opens up the specified
 * project and view.  Then, it searches through that view for the given
 * folder (or, if you prefer, it uses the root folder).  Beginning with
 * that folder and optionally continuing recursivesly, AntStarTeamCheckOut
 * compares each file with your include and exclude filters and checks it
 * out only if appropriate.
 * <BR><BR>
 * Checked out files go to a directory you specify under the subfolder
 * named for the default StarTeam path to the view.  That is, if you
 * entered /home/cpovirk/work as the target folder, your project was named
 * "OurProject," the given view was named "TestView," and that view is
 * stored by default at "C:\projects\Test," your files would be checked
 * out to /home/cpovirk/work/Test."  I avoided using the project name in
 * the path because you may want to keep several versions of the same
 * project on your computer, and I didn't want to use the view name, as
 * there may be many "Test" or "Version 1.0" views, for example.  This
 * system's success, of course, depends on what you set the default path
 * to in StarTeam.
 * <BR><BR>
 * You can set AntStarTeamCheckOut to verbose or quiet mode.  Also, it has
 * a safeguard against overwriting the files on your computer:  If the
 * target directory you specify already exists, the program will throw a
 * BuildException.  To override the exception, set <CODE>force</CODE> to
 * true.
 * <BR><BR>
 * <B>This program makes use of functions from the StarTeam API.  As a result
 * AntStarTeamCheckOut is available only to licensed users of StarTeam and
 * requires the StarTeam SDK to function.  You must have
 * <CODE>starteam-sdk.jar</CODE> in your classpath to run this program.
 * For more information about the StarTeam API and how to license it, see
 * the link below.</B>
