:: Automatic RDP Wrapper installer and updater             asmtron (2021-04-19)
:: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
:: Options:
::   -log        = redirect display output to the file autoupdate.log
::   -taskadd    = add autorun of autoupdate.bat on startup in schedule task
::   -taskremove = remove autorun of autoupdate.bat on startup in schedule task
::
:: Info:
::   The autoupdater first use and check the official rdpwrap.ini.
::   If a new termsrv.dll is not supported in the offical rdpwrap.ini,
::   autoupdater first tries the asmtron rdpwrap.ini (disassembled and
::   tested by asmtron). The autoupdater will also use rdpwrap.ini files
::   of other contributors like the one of "sebaxakerhtc, affinityv, DrDrrae, saurav-biswas".
::   Extra rdpwrap.ini sources can also be defined...
