  27 .Sh DESCRIPTION
  28 The
  29 .Nm
  30 utility extracts keywords from
  31 .Ux
  32 manuals and indexes them for fast retrieval.
  33 The arguments are as follows:
  34 .Bl -tag -width Ds
  35 .It Fl d Ar dir
  36 The directory into which to write the keyword and index databases.
  37 .It Ar

  46 By default,
  47 .Nm
  48 constructs the
  49 .Sx Index Database
  50 and
  51 .Sx Keyword Database
  52 in the current working directory.
  53 .Pp
  54 If fatal parse errors are encountered, the offending file is printed to
  55 stderr, omitted from the index, and the parse continues with the next
  56 input file.
  57 .Ss Index Database
  58 The index database,
  59 .Pa mandoc.index ,
  60 is a
  61 .Xr recno 3
  62 database with record values consisting of

  78 Both the manual section and description may be zero-length.
  79 Entries are sequentially-numbered, but the filenames are unordered.
  80 .Ss Keyword Database
  81 The keyword database,
  82 .Pa mandoc.db ,
  83 is a
  84 .Xr btree 3
  85 database of nil-terminated keywords (record length is non-zero string
  86 length plus one) mapping to a 8-byte binary field consisting of the
  87 keyword type and source
  88 .Sx Index Database
  89 record number.
  90 The type, an unsigned 32-bit integer in host order, is one of the
  91 following:
