## Name

mthelp — MiKTeX help utility

## Synopsis

`mthelp` [`option`...] {`name`...}

## Description

mthelp is a utility to lookup TeX package documentation.

mthelp creates an HTML page which contains a short description of the package together with links to all documentation files. An HTML viewer is started to view the page.

You can use the `--view` to bypass the intermediate HTML file.

`name` should be the name of a package in the TeX distribution.

## Options

`--list-only`

  List documentation files, but do not start a viewer.

`--print-only`

  Print the command that would be executed to view the documentation, but do not start the command.

`--quiet`

  Suppress all output, except errors.

`--version`

  Show version information and exit.

`--view`

  Open the main documenation file in a viewer.

## Environment

`MIKTEX_VIEW_dvi`

  DVI viewer.

`MIKTEX_VIEW_pdf`

  PDF viewer.

`MIKTEX_VIEW_ps`

  PostScript viewer.

`MIKTEX_VIEW_html`

  HTML viewer.

`MIKTEX_VIEW_txt`

  Text viewer.

The environment variables should be set with a “%f” as a placeholder for the name of the file. For example:

    > MIKTEX_VIEW_pdf="gv %f"

## Files

The intermediate HTML file (``package`.html`) is stored in the directory `miktex/mthelp` relative to the data TEXMF root.
