Hi Folks,

As indicated in ticket #284 I believe I've found a relatively robust 
method for cleanly adding directories to PATH without risk of duplicate 
entries.  There are now (about to be) 2 new batch files in the Shell 
package: inpath and addpath.

INPATH: Is the specified directory in PATH?||||The result is returned as 

0 if the pathVar path is found in PATH.
1 if the pathVar path is not found in PATH.
2 if pathVar is missing or undefined or if PATH is undefined.

Example use:

    |set test=c:\osgeo4w\bin|
    |call inPath test && (echo found) || (echo not found)|

ADDPATH:  Safely appends the path contained within variable pathVar to 
the end of PATH if and only if the path does not already exist within 
PATH. Use "/b" to prepend to beginning.

Example use:

    |addpath /b %OSGEO4W_ROOT%|

for detailed info on what these scripts do and how they're built.
