# Script to set up Macintosh to run BOINC client as a daemon / service
# by Charlie Fenton 7/26/06
##

## Usage:
##
## source Make_BOINC_Service.sh [path_to_client_dir/] [path_to_data_dir/]
##
## path_to_client_dir is needed only for stand-alone client or if Manager
##  is at non-standard location.
##
## path_to_data_dir is needed only for stand-alone client when data is in 
##  a different directory than the client.
##
## Directions for use:
##
## (1) Install BOINC Manager using the BOINC.pkg Installer Package, or 
##     install stand-alone client. 
## (2) Make sure you are logged in as a user with administrator 
##     privileges.
## (3) Run the Terminal application.
## (4) In the Terminal window, type "source" and a space.
## (5) Drag this script file from the Finder into the Terminal window.
## (6) If using the stand-alone client, or if the Manager is in a non-
##     standard location, drag the folder containing the client  from 
##     the Finder into the Terminal window (or type the path including 
##     the trailing slash).
## (7) If using the stand-alone client, but the client is not in the data 
##     directory, drag the BOINC data folder from the Finder into the 
##     Terminal window (or type the path including the trailing slash).
## (8) Press the return key.
## (9) When prompted, enter your administrator password.
## (10) Restart the computer.
##
## The system will now start BOINC client as a daemon / service at 
## system startup.  You will still be able to control and monitor BOINC 
## using the BOINC Manager, but BOINC client will remain running after 
## you quit BOINC Manager, when the ScreenSaver quits, and even when 
## no user is logged in.
##
## Note: the BOINC ScreenSaver may not display graphics for some users 
## when BOINC Client is running as a daemon / service.  We hope to fix 
## this in the near future.
##

## Removal (to stop running BOINC as a daemon / service):
## (1) In the Finder, browse to the /Library/StartupItems folder.
## (2) Drag the boinc directory to the trash.  (Finder will ask for 
##     your administrator user name and password).
## (3) Restart the computer.
##
## The system will no longer start BOINC client as a daemon / service 
## at system startup.  
##
## Running BOINC Manager will star BOINC Client.  This will happen 
## automatically at login if you have BOINC Manager set as a login item 
## for that user.  BOINC Client will quit when the BOINC Manager quits.
##
## If BOINC Client is not already running when the BOINC ScreenSaver 
## starts, the ScreenSaver will start BOINC Client and will quit 
## BOINC Client when the ScreenSaver is dismissed.
##
## If you wish to completely remove BOINC from your computer, first 
## complete the above steps, then follow the directions in the web 
## page http://boinc.berkeley.edu/mac_advanced.php or in the README.rtf 
## file supplied with the BOINC installer.
