  21 =head1 DESCRIPTION
  22
  23 This module is an abstraction of a lot of functions which originally
  24 were only present in service.in, but as time has gone on needed to be
  25 called from elsewhere.
  26
  27 All of the public functions take the following options:
  28
  29 =over
  30
  31 =item debug -- scalar reference to which debbuging information is
  32 appended
  33
  34 =item transcript -- scalar reference to which transcript information
  35 is appended
  36
  37 =item affected_bugs -- hashref which is updated with bugs affected by
  38 this function
  39
  40
  41 =back
  42
  43 Functions which should (probably) append to the .log file take the
  44 following options:
  45
  46 =over
  47
  48 =item requester -- Email address of the individual who requested the change
  49
  50 =item request_addr -- Address to which the request was sent
  51
  52 =item request_nn -- Name of queue file which caused this request
  53
  54 =item request_msgid -- Message id of message which caused this request
  55
  56 =item location -- Optional location; currently ignored but may be
  57 supported in the future for updating archived bugs upon archival
  58
  59 =item message -- The original message which caused the action to be taken
  60
  61 =item append_log -- Whether or not to append information to the log.
  62
  63 =back
  64
  65 B<append_log> (for most functions) is a special option. When set to
  66 false, no appending to the log is done at all. When it is not present,
  67 the above information is faked, and appended to the log file. When it
  68 is true, the above options must be present, and their values are used.
