These two pages discuss everything you could want to know.
http://developer.apple.com/documentation/MacOSX/Conceptual/SystemOverview/SoftwareConfig/chapter_11_section_4.html
http://developer.apple.com/documentation/Cocoa/Conceptual/UserDefaults/
The preferences format:
The most common preference file format is an xml file with the file extension
".plist" with this DTD:
http://www.apple.com/DTDs/PropertyList-1.0.dtd
I propose the code to be:
<key>LDRAWDIR</key>
<string>/Library/ldraw</string>
Or exactly:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
"http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>LDRAWDIR</key>
<string>/Library/ldraw</string>
</dict>
</plist>
This file can be saved at:
~/Library/Preferences/org.ldraw.ldrawdir.plist (for the current user only)
/Library/Preferences/org.ldraw.ldrawdir.plist (for all users of the computer)
The default permissions for /Libray/ is:
drwxrwxr-x 34 root admin
The default user is in the admin group, but any non-admin user, like kids who
use their parents' computer or users of a computer lab, is not in the admin
group. So the ldraw folder and a global preference file may not be writable.
So perhaps applications should check /Library and ~/Library for both ldraw dir
and org.ldraw.ldrawdir.plist. So:
/Library/ldraw
~/Library/ldraw
/Library/Preferences/org.ldraw.ldrawdir.plist
~/Library/Preferences/org.ldraw.ldrawdir.plist.
What do you think? Is this too much trouble?
