/* Customizable installer to allow use of features described at
http://boinc.berkeley.edu/client_startup.php
Directions for creating a customized installer for the Macintosh:
[1] Create a directory, with a name such as SETI@home_Mac_Installer
[2] Place this CustomInstall application inside that directory. You
may rename this application if you wish.
[3] Create a new directory named "boinc_startup_files" inside the
directory created in step 1.
[4] Place the custom .xml files in the "boinc_startup_files" directory.
[5] Zip the directory created in step 1 (with all its contents).
