  25 ;; INTRODUCTION
  26 ;; ------------
  27 ;; This package provides a major mode for editing SNMP MIBs.  It
  28 ;; provides all the modern Emacs 19 bells and whistles: default
  29 ;; fontification via font-lock, imenu search functions, etc.
  30 ;;
  31 ;; SNMP mode also uses tempo, a textual boilerplate insertion package
  32 ;; distributed with Emacs, to add in boilerplate SNMP MIB structures.
  33 ;; See tempo.el for more details about tempo.
  34 ;;
  35 ;; If you want to change or add new tempo templates, use the tempo tag
  36 ;; list `snmp-tempo-tags' (or `snmpv2-tempo-tags'): this list is
  37 ;; automatically installed when snmp-mode (or snmpv2-mode) is entered.
  38 ;;
  39 ;; The SNMPv2 mode in this version has been enhanced thanks to popular
  40 ;; demand.
  41 ;;
  42 ;; I'm very interested in new tempo macros for both v1 and v2, and any
  43 ;; other suggestions for enhancements (different syntax table items, new
  44 ;; keybindings, etc.)
  45 ;;
  46 ;;
  47 ;; USAGE
  48 ;; -----
  49 ;; Mostly, use it as you would any other mode.  There's a very
  50 ;; simplistic auto-indent feature; hopefully it'll help more than get in
  51 ;; your way.  For the most part it tries to indent to the same level as
  52 ;; the previous line.  It will try to recognize some very simple tokens
  53 ;; on the previous line that tell it to use extra indent or outdent.
  54 ;;
  55 ;; Templates
  56 ;; ---------
  57 ;; To use the Tempo templates, type the Tempo tag (or a unique prefix)
  58 ;; and use C-c C-i (C-c TAB) to complete it; if you don't have
  59 ;; tempo-interactive set to nil it will ask you to fill in values.
  60 ;; Fields with predefined values (SYNTAX, STATUS, etc.) will do
  61 ;; completing-reads on a list of valid values; use the normal SPC or TAB
  62 ;; to complete.
  63 ;;
  64 ;; Currently the following templates are available:
  65 ;;
  66 ;;  objectType -- Defines an OBJECT-TYPE macro.
  67 ;;
  68 ;;  tableType  -- Defines both a Table and Entry OBJECT-TYPE, and a
  69 ;;                SEQUENCE for the ASN.1 Entry definition.
  70 ;;
  71 ;; Once the template is done, you can use C-cC-f and C-cC-b to move back
  72 ;; and forth between the Tempo sequence points to fill in the rest of
  73 ;; the information.
  74 ;;
  75 ;; Font Lock
  76 ;; ------------
  77 ;;
  78 ;; If you want font-lock in your MIB buffers, add this:
  79 ;;
  80 ;;  (add-hook 'snmp-common-mode-hook 'turn-on-font-lock)
  81 ;;
  82 ;; Enabling global-font-lock-mode is also sufficient.
  83 ;;

  88   (require 'imenu))   ; Need this stuff when compiling for imenu macros, etc.
