My earlier message was wrong, addpath is used by setting a variable first:
{{{
set _path=%OSGEO4W_ROOT%bin
call %OSGEO4W_ROOT%\bin\addpath.bat _path
set _path=
}}}
I'm not sure why the author uses that method when passing the actual
desired path would be more straightforward, from a user's point of view.
However as I don't understand everything the file does I'm not going to
mess with it just yet.
The above is now part of pkg-shell v 1.0.0-9, which has been tested and
works on my machine. I promoted it to regular use. More testing and
feedback welcome.
cheers,

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
the ERRORLEVEL:
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%|
||
