The version output contains two paragraphs.  The first paragraph
    details the version number, and the version number of any major
    libraries in use.  The second paragraph details known and supported
    passphrase derivation schemes, foreign configuration formats,
    subcommands, SSH agent socket providers and PEP 508 package extras.

For the schemes, formats and socket providers, there is
    a "supported" line for supported items, and a "known" line for known
    but currently unsupported items (usually because of missing
    dependencies), either of which may be empty and thus omitted.  For
    extras, only active items are shown, and there is a separate message
    for the "no extras active" case.  Items may be followed by a list of
    aliases, explicitly marked as such.  Item lists may be spilled
    across multiple lines, but only at item boundaries.  (The alias list
    counts as part of the same item.)  The continuation lines are then
    indented.

The list of aliases is formatted as `<name> (aliases: <alias1>,
    <alias2>)`.  Only one level of aliases is supported, and neither
    `<name>` nor `<alias>` must contain parentheses.  (Brackets and
    braces are discouraged, but not expressly forbidden.)

Args:
        version_output:
            The version output text to parse.
        prog_name:
            The program name to assert, defaulting to the true program
            name, `derivepassphrase`.  Set to `None` to disable this
            check.
        version:
            The program version to assert, defaulting to the true
            current version of `derivepassphrase`.  Set to `None` to
            disable this check.
