* Module: billboard.c
*
* Description: billboard.c
* Billboard is an RPC program that handles information about
* testsuites completions. The module here is the user program
* that communicates with the billboard server. This program
* allows user to update and modify information maintained
* by the server. The features supported are (described below
* using the command line options):
* i) -s <client identifier> <server identifier>
* to set test between <client identifier> and
* <server identifier> as successfully tested
* ii) -u <client identifier> <server identifier>
* to set test between <client identifier> and
* <server identifier> as NOT successfully tested
* iii) -a <client identifier>
* to list server implementations that are successfully
* tested against client <client identifier>
* iv) -b <client identifier>
* to list server implementations that are NOT
* successfully tested against client <client identifier>
* v) -c <server identifier>
* to list client implementations that are successfully
* tested against server <server identifier>
* vi) -d <server identifier>
* to list client implementations that are NOT
* successfully tested against server <server identifier>
* vii) -p <identifier>
* to change the password of the <identifier>
* implementation
*
* where <client identifier> and <server identifier> is
* identifier of the client and server implementation
* respectively.
*
* This user program also supports interactive interface whereby
* the user is presented with a list of options (same as the
* features described above) to choose from. User will be prompted
* for any additional data.
*
* Functions:
* main(argc, argv)
* _cmd_line_option(argc, argv)
* _interactive_option()
* _bb_get_passwd(bb_passwd_in_p)
*
