Dude, I know that "|" is for pipe, but - - is for stdio in terms of xtool

The usage for xtool goes like this

xtool command input output
"-" denotes stdin/stdout depending where you put it.

This is how I have written it

  
if ParamArg[2] = '-' then
    Output := THandleStream.Create(GetStdHandle(STD_OUTPUT_HANDLE))
  else
    Output := TFileStream.Create(ParamArg[2], fmCreate);

The reason I have added it as "-"

is because what if you can accept input as stdin then the next program requires an existing file
it then becomes something like this

xtool command - output

or if input is a file and output is required as stdout
it becomes
xtool command input -

if pipes are involved it means stdin and stdout takes place which is why it is
xtool command - -
