   1 /*
   2  * roleplay commands for solanum.
   3  *
   4  * adds NPC, NPCA, and SCENE which allow users to send messages from 'fake'
   5  * nicknames. in the case of NPC and NPCA, the nickname will be underlined
   6  * to clearly show that it is fake. SCENE is a special case and not underlined.
   7  * these commands only work on channels set +N
   8  *
   9  * also adds oper commands FSAY and FACTION, which are like NPC and NPCA
  10  * except without the underline.
  11  *
  12  * all of these messages have the hostmask npc.fakeuser.invalid, and their ident
  13  * is the nickname of the user running the commands.
