/*
* Source file that is rebuilt per application, and provides the list
* of backends, the default protocol, and the application name.
*
* This file expects the build system to provide some per-application
* definitions on the compiler command line. So you don't just add it
* directly to the sources list for an application. Instead you call
* the be_list() function defined in setup.cmake, e.g.
*
* be_list(target-name AppName [SSH] [SERIAL] [OTHERBACKENDS])
*
* This translates into the following command-line macro definitions
* used by the code below:
*
* - APPNAME should be defined to the name of the program, in
* user-facing capitalisation (e.g. PuTTY rather than putty).
* Unquoted: it's easier to stringify it in the preprocessor than
* to persuade cmake to put the right quotes on the command line on
* all build platforms.
*
* - The following macros should each be defined to 1 if a given set
* of backends should be added to the backends[] list, or 0 if they
* should not be:
*
* * SSH: the two SSH backends (SSH proper, and bare-ssh-connection)
*
* * SERIAL: the serial port backend
*
* * OTHERBACKENDS: the non-cryptographic network protocol backends
* (Telnet, Rlogin, SUPDUP, Raw)
