rem First, check if this is DOS based system
rem in DOS '^' is just a normal character
if not ^x==x goto DOS
rem Abort if we are running from UNC path
if %~d0==\\ goto UNC
rem Localize environment changes
setlocal enableextensions
rem Do we really need to cd to the batch location?
cd /d "%~dp0"
rem Remove any double quotes from PATH (why we care for it at all???)
set "path=%path:"=%"
rem Break search path into dir list and rebuild w/o tex dirs
call :rebuildpath ";" "%path:;=" "%"
if "%path:~0,1%"==";" set "path=%path:~1%"
rem Use TL Perl
set "path=%~dp0tlpkg\tlperl\bin;%path%"

rem About install-tl.bat.manifest:
rem Vista assumes that a file with install in the name is
rem an installer and therefore requires administrative privileges.
rem The manifest file tells Vista otherwise.
:UNC
echo Cannot run from UNC path.
echo Map network drive to a drive letter and rerun the installer.
echo You can use pushd/popd commands for temporary mapping.

exit /b 1
:DOS
echo DOS and Windows 9x systems are not supported. Sorry.
echo Windows 2000 or newer is required.
