/* PostInstall.cpp */
// Notes on command-line installation to a remote Mac:
//
// When the installer is run from the Finder, this Postinstall.app will
// display up to two dialogs, asking the user whether or not to:
// [1] allow non-administrative users to run the BOINC Manager
// (asked only if this Mac has any non-administrative users)
// [2] set BOINC as the screensaver for all users who can run BOINC
// (asked only if BOINC screensaver is not already set for them)
//
// The installer can also be run from the command line. This is useful
// for installation on remote Macs. However, there is no way to respond
// to dialogs during a command-line install.
//
// The command-line installer sets the following environment variable:
// COMMAND_LINE_INSTALL=1
// The postinstall script, postupgrade script, and this Postinstall.app
// detect this environment variable and do the following:
// * Redirect the Postinstall.app log output to a file
// /tmp/BOINCInstallLog.txt
// * Suppress the 2 dialogs
// * test for the existence of a file /tmp/nonadminusersok.txt; if the
// file exists, allow non-administrative users to run BOINC Manager
// * test for the existence of a file /tmp/setboincsaver.txt; if the
// file exists, set BOINC as the screensaver for all BOINC users.
//
// Example: To install on a remote Mac from the command line, allowing
// non-admin users to run the BOINC Manager and setting BOINC as the
// screensaver:
// * First SCP the "BOINC Installer.pkg" to the remote Mac's /tmp
// directory, then SSh into the remote mac and enter the following
// $ touch /tmp/nonadminusersok.txt
// $ touch /tmp/setboincsaver.txt
// $ sudo installer -pkg "/tmp/BOINC Installer.pkg" -tgt /
// $ sudo reboot
