I disagree. If you run an app and it cannot find say libX, then you should just
be able to specify where libX is on the command line, rather than libX, and
machine.e, and win32lib/wxEuphoria, etc. Of course look where the command line
says first, but if you do not find it I can think of no reason to prohibit
looking elsewhere.

Perhaps. You might equally want a semicolon separator in the -i option.

 From a windows perspective, if you're running C:\euphoria\bin\exw.exe then
obviusly it ought to look for includes in C:\euphoria\include\. I would
therefore expect there to be a file C:\euphoria\bin\euinc.conf (ie same dir as
exw.exe) which contains the relative path "..\include\" (and/or attempt that as a
last resort if no config file can be found). IMO relative paths should be
relative to the location of the .conf file they are specified in,
and a -i relative path should be relative to the current directory.

You may also want a special notation such as "%%..\include\" whereby the %% is
replaced with the location of exu/exw.exe.

Personally I would reword that as:
   * command line switches
         * -c <config file>
         * -i <directory of euinc.conf>

Lastly, can you add a note that if %APPDATA% and/or %ALLUSERSPROFILE% do not
exist then the corresponding step is skipped (rather than crash/error out).
