NAME
    mkpkgconfig - create pkg-config metadata files

VERSION
    version v2.0.2

SYNOPSIS
    mkpkgconfig *options*

DESCRIPTION
    mkpkgconfig creates a pkg-config metadata (".pc") file. pkg-config
    variables and keywords are defined on the command line, variable
    dependencies are validated, and the configuration file is output.
    "Standard" variables (such as $libdir, $datadir) may be automatically
    created, and only variables which are used are output.

  Variables and Keywords
    pkg-config distinguishes between *variables* and *keywords*. Values for
    both may include interpolated variables, as in "Cflags: -I ${include}".

    Some commonly used variables have dedicated command line options:

      --prefix     : base prefix for paths
      --package    : filesystem compatible package name
      --modversion : package version

    ("--modversion" sets the *version* variable; the "--version" flag will
    output the version of "mkpkgconfig").

    "--modversion" is required. "--prefix" and "--package" may be required
    if a keyword requires them or "--auto" is set and auto-generated
    variables require it.

    Common keywords also have dedicated options:

      --Name
      --Conflicts
      --Description
      --Requires
      --Libs
      --Cflags
      --URL

    The "--Name" and "--Description" options are required. The "Version"
    keyword is automatically set to "${version}". It is not possible to set
    it directly from the command line.

    Other variables and keywords may be specified via the "--var" and
    "--kwd" options, respectively:

      --var name=value
      --kwd name=value

    which may be used more than once.

  Automatically Generated Variables
    "mkpkgconfig" can automatically generate a number of "standard"
    variables, such as *bindir*, *libdir*, etc, based upon the *prefix*
    variable. Use the "--list-auto" option to output a list of these
    variables.

OPTIONS
  General Options
    --output
        Where the configuration file is to be written. It defaults to the
        standard output stream.

    --usevars "all"|"requested"|"needed"
        Which variables should be output. It defaults to "needed".

        "all"
            output all variables, needed or not, including automatically
            generated ones if "--auto" was specified;

        "requested"
            output only requested variables (via-"-var variable=value" or
            "--auto=variable,...") and keyword dependencies;

        "needed"
            output only those variables actually used by keywords

  Variables
    "--var" *name*=*value*
        Set the variable named *name* to *value*.

    "--prefix" *value*
        Set the "prefix" variable.

    "--package" *value*
        Set the "package" variable

    "--modversion" *value*
        Set the "version" value

    "--auto"
    "--auto" *list of variables*
        Generate a set of variables. Use "--list-auto" to see what is
        generated.

        If passed a list of variable names, those will be output if
        "--usevars" is set to "requested".

        Individual variables may be overriden using "--var".

    "--list-auto"
        Output a list of the automatically generated keywords and exit.

   Keywords
    "--kwd" *name*=*value*
        Set the keyword named *name* to *value*.

    "--Name" *value*
    "--name" *value*
        Set the *Name* keyword. This parameter is required.

    "--Description" *value*
    "--description" *value*
        Set the *Description* keyword. This parameter is required.

    "--Requires" *value*
    "--requires" *value*
        Set the *Requires* keyword.

    "--Conflicts" *value*
    "--conflicts" *value*
        Set the *Conflicts* keyword.

    "--Libs" *value*
    "--libs" *value*
        Set the *Libs* keyword.

    "--Cflags" *value*
    "--cflags" *value*
        Set the *Cflags* keyword.

  Miscellaneous
    --version
        Output the version of mkpkgconfig and exit.

    --help
        Output a short help message and exit.

    --manual
        Output the manual and exit.
