  23.      This procedure may be invoked to use the Tk event management functions
  24.      without the rest of Tk (e.g., in applications that do not have access to
  25.      a display).  TTTTkkkk____EEEEvvvveeeennnnttttIIIInnnniiiitttt creates the aaaafffftttteeeerrrr and ffffiiiilllleeeeeeeevvvveeeennnntttt commands in
  26.      _i_n_t_e_r_p.  It also creates versions of the ttttkkkkwwwwaaaaiiiitttt and uuuuppppddddaaaatttteeee commands with
  27.      reduced functionality:  the ttttkkkkwwwwaaaaiiiitttt command supports only the vvvvaaaarrrriiiiaaaabbbblllleeee
  28.      option, not vvvviiiissssiiiibbbbiiiilllliiiittttyyyy or wwwwiiiinnnnddddoooowwww, and uuuuppppddddaaaatttteeee does not check for X events.
  29.      TTTTkkkk____EEEEvvvveeeennnnttttIIIInnnniiiitttt always returns TTTTCCCCLLLL____OOOOKKKK to signal that it completed
  30.      successfully.
  31.  
  32.      The event-management procedures in Tk are divided into two groups, those
  33.      that can be used stand-alone and those that require the full Tk library
  34.      to be present.  The following procedures may be used stand-alone:
  35.      TTTTkkkk____CCCCrrrreeeeaaaatttteeeeFFFFiiiilllleeeeHHHHaaaannnnddddlllleeeerrrr, TTTTkkkk____CCCCrrrreeeeaaaatttteeeeFFFFiiiilllleeeeHHHHaaaannnnddddlllleeeerrrr2222, TTTTkkkk____DDDDeeeelllleeeetttteeeeFFFFiiiilllleeeeHHHHaaaannnnddddlllleeeerrrr,
  36.      TTTTkkkk____CCCCrrrreeeeaaaatttteeeeTTTTiiiimmmmeeeerrrrHHHHaaaannnnddddlllleeeerrrr, TTTTkkkk____DDDDeeeelllleeeetttteeeeTTTTiiiimmmmeeeerrrrHHHHaaaannnnddddlllleeeerrrr, TTTTkkkk____DDDDooooWWWWhhhheeeennnnIIIIddddlllleeee,
  37.      TTTTkkkk____CCCCaaaannnncccceeeellllIIIIddddlllleeeeCCCCaaaallllllll, TTTTkkkk____DDDDooooOOOOnnnneeeeEEEEvvvveeeennnntttt, TTTTkkkk____SSSSlllleeeeeeeepppp, and TTTTkkkk____BBBBaaaacccckkkkggggrrrroooouuuunnnnddddEEEErrrrrrrroooorrrr.  Note
  38.      that TTTTkkkk____MMMMaaaaiiiinnnnLLLLoooooooopppp cannot be used without the full Tk library, since it
  39.      checks to see if windows are still open.  If an application uses the
  40.      event procedures stand-alone, it must include its own main loop that
  41.      invokes TTTTkkkk____DDDDooooOOOOnnnneeeeEEEEvvvveeeennnntttt repeatedly.
  42.  
  43.      TTTTkkkk____EEEEvvvveeeennnnttttIIIInnnniiiitttt is typically called from an application's TTTTccccllll____AAAAppppppppIIIInnnniiiitttt
  44.      procedure;  it should not be invoked in applications that use the full Tk
  45.      library (e.g., those that have already invoked TTTTkkkk____CCCCrrrreeeeaaaatttteeeeMMMMaaaaiiiinnnnWWWWiiiinnnnddddoooowwww).
  46.      However, it is OK for an application to start up using TTTTkkkk____EEEEvvvveeeennnnttttIIIInnnniiiitttt,
  47.      compute without X for a while, and later invoke TTTTkkkk____CCCCrrrreeeeaaaatttteeeeMMMMaaaaiiiinnnnWWWWiiiinnnnddddoooowwww.
  48.      When TTTTkkkk____CCCCrrrreeeeaaaatttteeeeMMMMaaaaiiiinnnnWWWWiiiinnnnddddoooowwww is invoked, the full suite of windowing Tcl
  49.      commands will become available, and the full-blown versions of ttttkkkkwwwwaaaaiiiitttt and
  50.      uuuuppppddddaaaatttteeee will replace the abridged versions created with TTTTkkkk____EEEEvvvveeeennnnttttIIIInnnniiiitttt.
