GNAT Expect g-expect ads (GNAT Reference Manual)

### 13.70 `GNAT.Expect` (`g-expect.ads`) ¶

Provides a set of subprograms similar to what is available with the standard Tcl Expect tool. It allows you to easily spawn and communicate with an external process. You can send commands or inputs to the process, and compare the output with some expected regular expression. Currently `GNAT.Expect` is implemented on all native GNAT ports. It is not implemented for cross ports, and in particular is not implemented for VxWorks or LynxOS.
