  26 .Ar
  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
  38 Read input from zero or more files in
  39 .Xr mdoc 7
  40 or
  41 .Xr man 7
  42 .Ux
  43 manual format.
  44 .El
  45 .Pp
  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 of nil-terminated filenames (record length is non-zero string
  63 length plus one) passed to
  64 .Nm .
  65 Entries are sequentially-numbered, but the filenames are unordered.
  66 .Ss Keyword Database
  67 The keyword database,
  68 .Pa mandoc.db ,
  69 is a
  70 .Xr btree 3
  71 database of nil-terminated keywords (record length is non-zero string
  72 length plus one) mapping to a 8-byte binary field consisting of the
  73 keyword type and source
  74 .Sx Index Database
  75 record number.
  76 The type, an unsigned 32-bit integer in host order, is one of the
  77 following:
  78 .Pp
  79 .Bl -tag -width Ds -offset indent -compact
  80 .It Li 0x01
  81 The name of a manual page as given in the NAME section.
  82 .It Li 0x02
  83 A function prototype name as given in the SYNOPSIS section.
  84 .It Li 0x03
  85 A utility name as given in the SYNOPSIS section.
  86 .It Li 0x04
  87 An include file as given in the SYNOPSIS section.
  88 .It Li 0x05
  89 A variable name as given in the SYNOPSIS section.
  90 .El
  91 .Pp
  92 If a value is encountered outside of this range, the database is
  93 corrupt.
  94 .Pp
  95 The latter four bytes are a host-ordered record number within the
  96 .Sx Index Database .
