/**
<unit>
<heading>Path Utility Functions</heading>
<p>
Path utilities provides functions to dynamically discover paths
for the platform the application is running on.
This avoids the need for hard coding paths, making porting easier
and also allowing for places to change without breaking
applications.
(why do this? Well imagine we're running GNUstep 1 and the new
wonderful GNUstep 2 becomes available but we're not sure of it
yet. You could install /GNUstep/System2/ and have applications
use which ever System you wanted at the time...)
</p>
<p>
On unix systems, the paths are initialised by reading a configuration
file. Something like "/etc/GNUstep/GNUstep.conf". This provides the basic
information required by the library to establish all locations required.
</p>
<p>
See <REF "filesystem.pdf">GNUstep File System Hierarchy</REF> document
for more information and detailed descriptions.</p>

/**
* Reads a file and expects it to be in basic unix "conf" style format with

* to define shell variables).<br />
* This attempts to mimic the escape sequence and quoting conventions of
* the standard bourne shell, so that a config file sourced by the make
* package will produce the same results as one parsed by this function.<br />
* Keys, by convention, consiste of uppercase letters, digits,
* and underscores, and must not begin with a digit.<br />
* A value may be any quoted string (or an unquoted string containing no
* white space).<br />
* Lines beginning with a hash '#' are deemed comment lines and ignored.<br/ >
* The backslash character may be used as an escape character anywhere
* in the file except within a singly quoted string
* (where it is taken literally).<br />
* A backslash followed immediately by a newline (except in a singly
* quoted string) is removed completely along with the newline ... it
* thus serves to join lines so that they are treated as a single line.<br />
* NB. Since ms-windows uses backslash characters in paths, it is a good
* idea to specify path values in the config file as singly quoted
* strings to avoid having to double all occurrences of the backslash.<br />
* Returns a dictionary of the (key,value) pairs.<br/ >
* If the file does not exist,
