Delphi IDE - Command line switches and explanation

where I can get a Delphi XE list of command line switches to startup bds (delphi) ?

For the moment, I know this:

-pDelphi -> when use it ? (install d开发者_StackOverflowefault)

-nocache -> when use it

But I can startup bds without any of them. Even the default: -pDelphi

These switches are documented: http://docwiki.embarcadero.com/RADStudio/en/IDE_Command_Line_Switches_and_Options
