* Some global flags denoting the type of application.
|
|
*
|
|
* FLAG_VERBOSE is set when the user requests verbose details.
|
|
*
|
|
* FLAG_STDERR is set in command-line applications (which have a
|
|
* functioning stderr that it makes sense to write to) and not in
|
|
* GUI applications (which don't).
|
|
*
|
|
* FLAG_INTERACTIVE is set when a full interactive shell session is
|
|
* being run, _either_ because no remote command has been provided
|
|
* _or_ because the application is GUI and can't run non-
|
|
* interactively.
|
|
*
|
|
* These flags describe the type of _application_ - they wouldn't
|
|
* vary between individual sessions - and so it's OK to have this
|
|
* variable be GLOBAL.
|
|
*
|
|
* Note that additional flags may be defined in platform-specific
|
|
* headers. It's probably best if those ones start from 0x1000, to
|
|
* avoid collision.
