*
|

* There are two variants of BIRD client: regular and light. regular
|
||||
* variant depends on readline and ncurses libraries, while light
|
||||
* variant uses just libc. Most of the code and the main() is common
|
||||
* for both variants (in client.c file) and just a few functions are
|
||||
* different (in birdc.c for regular and birdcl.c for light). Two
|
||||
* binaries are generated by linking common object files like client.o
|
||||
* (which is compiled from client.c just once) with either birdc.o or
|
||||
* birdcl.o for each variant.
