    <title>Description</title>
    <para>The <command>pwm</command> utility is a password manager which
    stores passwords and associated metadata in an encrypted database protected
    by a master password.  It offers both a text-based user interface for
    interactive use as well as a non-interactive mode.  The database uses the
    PasswordSafe database version 3 file format and thus provides
    interoperabity with other password managers using the same format.</para>
    <para>After opening an existing database or creating a new one,
    <command>pwm</command> provides commands to create, modify, delete, and
    display password database entries which may be organized in groups.  The
    contents of a field of a given entry can also be piped to an external
    command such as the <citerefentry><refentrytitle>pwm-clip</refentrytitle>
    <manvolnum>1</manvolnum></citerefentry> utility in order to copy the
    content of the username or password field of an entry to the
    clipboard.</para>
    <para>If specified, <command>pwm</command> will open or create
    <replaceable>database_file</replaceable> instead of the user's default
    database.</para>
    <para><command>pwm</command> must be run with a locale which uses the UTF-8
    character encoding.</para>
    <refsect2>
      <title>Output format</title>
      <para>The <command>show</command> and <command>info</command> commands
      display fields by printing the field name followed by a colon, one or
      more space characters and the field's verbatim content to the standard
      output stream. Field content may contain newlines, non-printable and/or
      control characters.</para>
      <para>If running in interactive mode, the <command>list</command>,
      <command>show</command> and <command>info</command> will display
      the results on a page-by-page basis using an internal pager.</para>
      <para>The <command>pipe</command> prints the verbatim field content to the
      standard input stream of the given command.</para>
      <para>Error messages are printed to the standard error stream.</para>

    <title>Usage</title>
    <refsect2>
      <title>Start-up</title>
      <para>If stdin is connected to a terminal pwm will run in interactive mode
      and prompt the user for the master password unless
      <replaceable>password_file</replaceable> is specified via the
      <option>-P</option> option. After successfully opening the password
      database the user will be prompted for a command.</para>
      <para>When running in non-interactive mode a file containing the master
      pasword must be specified via the <option>-P</option> option and after
      successfully opening the password database, pwm will execute commands
      read from stdin until either an error occurrs or end-of-file is
      reached.</para>
      <para><command>pwm</command> operates on a copy of the password database
      in memory, any changes must be explicitly written back to the database
      using the write command.</para>
      <para>When starting up, before prompting the user for a master password
      or reading the master password from a specified file
      <command>pwm</command> will read the file
      <filename>~/.pwm/pwmrc</filename> and execute any <command>set</command>
      and <command>define</command> commands specified therein.</para>
    </refsect2>
    <refsect2>
      <title>Configuration Variables</title>
      <para><command>pwm</command> can be configured through configuration
      variables using the <command>set</command> command. The following
      configuration variables are supported:</para>

        <varlistentry>
          <term>filename</term>
          <listitem>

      <title>Commands</title>
      <para>Each command must appear on a seperate line terminated by a newline
      character.  The command and its arguments are seperated by whitespace,
      i.e. one or more space or tab characters.  If an argument contains
      whitespace characters it must either be quoted by encosing it in single
      or double quote characters or each whitespace character must be preceded
      by a backslash character.  Arguments quoted with a single or double quote
      character preserve the literal values of all characters with the
      exception of the backslash character which can be used to escape the
      respective quoting character.  Two consecutive backslash characters yield
      a literal backslash within both quoted and unquoted arguments. A line
      must not end in a single backslash character, any other backslash
      characters are ignored.</para>
      <para>If an error occurrs while parsing or executing a command,
      <command>pwm</command> will terminate when running in non-interactive
      mode.  In interactive mode it will print an error message and prompt the
      user for the next command.  The following commands are supported:</para>

            <para>Define the macro <replaceable>name</replaceable> to expand to
            <replaceable>value</replaceable>.  A Macro is a shorthand term for
            a command and/or command arguments.  Macros are tokenized when they
            are defined, thus if a macro contains other macros, these other
            macros are expanded once at the time the macro is defined and not
            each time a macro is expanded later.  A macro can be used as like a
            command or as part of the command's argument by prefixing the macro
            name by a &quot;$&quot;. It is expanded by substituting the
            previously tokenized contents before the command is
            evaluated.</para>
