When the web server's CGI environment is mapped from programs in a
specific directory (e.g.
/cgi-bin), Vortex scripts are specified
in URLs as a path appended to the
texis program URL
With most CGI programs, this path (the PATH_INFO CGI variable)
is interpreted as relative to the server's document root (i.e. where
HTML documents are). However, Vortex uses its own
directory instead of document root, to avoid file permission
ScriptRoot defaults to the
texis/scripts subdirectory of
the install dir (see here to re-configure).
Thus, if Vortex is installed such that its URL is
/cgi-bin/texis, the URL
would execute the Vortex script
/usr/local/morph3/texis/scripts/myVortexScript (standard Unix
Windows Texis install).
