  46 .Sh DESCRIPTION
  47 The
  48 .Nm
  49 utility extracts keywords from
  50 .Ux
  51 manuals and indexes them in a database for fast retrieval by
  52 .Xr apropos 1 ,
  53 .Xr whatis 1 ,
  54 and
  55 .Xr man 1 Ns 's
  56 .Fl k
  57 option.
  58 .Pp
  59 By default,
  60 .Nm
  61 creates a database in each
  62 .Ar dir
  63 using the files
  64 .Sm off
  65 .Sy man Ar section Li /
  66 .Op Ar arch Li /
  67 .Ar title . section
  68 .Sm on
  69 and
  70 .Sm off
  71 .Sy cat Ar section Li /
  72 .Op Ar arch Li /
  73 .Ar title . Sy 0
  74 .Sm on
  75 in that directory.
  76 Existing databases are replaced.
  77 If a directory contains no manual pages, no database is created in that
  78 directory.
  79 If
  80 .Ar dir
  81 is not provided,
  82 .Nm
  83 uses the default paths stipulated by
  84 .Xr man.conf 5 .
  85 .Pp
  86 The arguments are as follows:
  87 .Bl -tag -width "-C file"
  88 .It Fl a
  89 Use all directories and files found below
  90 .Ar dir ... .
  91 .It Fl C Ar file
  92 Specify an alternative configuration
  93 .Ar file
  94 in
  95 .Xr man.conf 5
  96 format.
  97 .It Fl D
  98 Display all files added or removed to the index.
  99 With a second
 100 .Fl D ,
 101 also show all keywords added for each file.
 102 .It Fl d Ar dir
 103 Merge (remove and re-add)
 104 .Ar
 105 to the database in
 106 .Ar dir .
 107 .It Fl n
 108 Do not create or modify any database; scan and parse only,
 109 and print manual page names and descriptions to standard output.
 110 .It Fl p
 111 Print warnings about potential problems with manual pages
 112 to the standard error output.
 113 .It Fl Q
 114 Quickly build reduced-size databases
 115 by reading only the NAME sections of manuals.
 116 The resulting databases will usually contain names and descriptions only.
 117 .It Fl T Cm utf8
 118 Use UTF-8 encoding instead of ASCII for strings stored in the databases.
 119 .It Fl t Ar
 120 Check the given
 121 .Ar files
 122 for potential problems.
 123 Implies
 124 .Fl a ,
 125 .Fl n ,
 126 and
 127 .Fl p .
 128 All diagnostic messages are printed to the standard output;
 129 the standard error output is not used.
 130 .It Fl u Ar dir
 131 Remove
 132 .Ar
 133 from the database in
 134 .Ar dir .
 135 If that causes the database to become empty, also delete the database file.
 136 .El
 137 .Pp
 138 If fatal parse errors are encountered while parsing, the offending file
 139 is printed to stderr, omitted from the index, and the parse continues
 140 with the next input file.
 141 .Sh ENVIRONMENT
 142 .Bl -tag -width MANPATH
 143 .It Ev MANPATH
 144 A colon-separated list of directories to create databases in.
 145 Ignored if a
 146 .Ar dir
 147 argument or the
 148 .Fl t
 149 option is specified.
 150 .El
 151 .Sh FILES
 152 .Bl -tag -width Ds
 153 .It Pa mandoc.db
 154 A database of manpages relative to the directory of the file.
 155 This file is portable across architectures and systems, so long as the
 156 manpage hierarchy it indexes does not change.
 157 .It Pa /etc/man.conf
 158 The default
 159 .Xr man 1
 160 configuration file.
 161 .El
 162 .Sh EXIT STATUS
 163 The
 164 .Nm
 165 utility exits with one of the following values:
 166 .Pp
 167 .Bl -tag -width Ds -compact
 168 .It 0
 169 No errors occurred.
 170 .It 5
 171 Invalid command line arguments were specified.
 172 No input files have been read.
 173 .It 6
 174 An operating system error occurred, for example memory exhaustion or an
 175 error accessing input files.
 176 Such errors cause
 177 .Nm
 178 to exit at once, possibly in the middle of parsing or formatting a file.
 179 The output databases are corrupt and should be removed.
