Some parameters are used to tell each application where to find
certain files and folders.
The parameter values consist of one or more strings in the form of path names.
A path name can be a simple file name, or it can be a sequence of names
separated by colons that represent a valid location in your folder hierarchy.
If the path name ends with a colon then it specifies a folder, otherwise a file.
Path names must be enclosed in double quotes if they contain any spaces;
e.g., ":My PK files:".
NOTE: Because 's path names are also used by dvips, you cannot use
a comma in those paths; if you do you'll get an error message when the
config file is loaded. This is because commas are used to separate
dvips search paths (the standard version of dvips uses colons,
but they can't be used on the Mac).
Partial path names begin with a colon. The first folder in such a path is
assumed to be in the same location as the application. This is the best
way to specify folders and files because then you can move the entire
folder anywhere you like without having to change any path names.
Full path names begin with the name of a disk; e.g., HD:OzTeX:VF-files:.
Each application will generate a warning message if a given path name
does not specify a known folder or file.
Note that under System 7 or later, aliased files are supported,
but not aliased folders.
