; Macro for executing external applications. Uses the nsExec plugin
; in different styles, depending on whether this installer runs in silent mode
; or not. If the external program reports an exit code other than 0 the installer
; will be aborted.
;
; @param   Command line (full qualified and quoted).
; @param   If set to "true" the installer aborts if the external program reports
;          an exit code other than 0, "false" just prints a warning and continues
;          execution.
