+class Modula2Lexer(RegexLexer):
+    """
+    For `Modula-2 <http://www.modula2.org/>`_ source code.
+
+    The Modula-2 lexer supports several dialects.  By default, it operates in
+    fallback mode, recognising the *combined* literals, punctuation symbols
+    and operators of all supported dialects, and the *combined* reserved words
+    and builtins of PIM Modula-2, ISO Modula-2 and Modula-2 R10, while not
+    differentiating between library defined identifiers.
+
+    To select a specific dialect, a dialect option may be passed
+    or a dialect tag may be embedded into a source file.
+
+    Dialect Options:
+
+    `m2pim`
+        Select PIM Modula-2 dialect.
+    `m2iso`
+        Select ISO Modula-2 dialect.
+    `m2r10`
+        Select Modula-2 R10 dialect.
+    `objm2`
+        Select Objective Modula-2 dialect.
+
+    The PIM and ISO dialect options may be qualified with a language extension.
+
+    Language Extensions:
+
+    `+aglet`
+        Select Aglet Modula-2 extensions, available with m2iso.
+    `+gm2`
+        Select GNU Modula-2 extensions, available with m2pim.
+    `+p1`
+        Select p1 Modula-2 extensions, available with m2iso.
+    `+xds`
+        Select XDS Modula-2 extensions, available with m2iso.
+
+
+    Passing a Dialect Option via Unix Commandline Interface
+
+    Dialect options may be passed to the lexer using the `dialect` key.
+    Only one such option should be passed. If multiple dialect options are
+    passed, the first valid option is used, any subsequent options are ignored.
+
+    Examples:
+
+    `$ pygmentize -O full,dialect=m2iso -f html -o /path/to/output /path/to/input`
+        Use ISO dialect to render input to HTML output
+    `$ pygmentize -O full,dialect=m2iso+p1 -f rtf -o /path/to/output /path/to/input`
+        Use ISO dialect with p1 extensions to render input to RTF output
+
+
+    Embedding a Dialect Option within a source file
+
+    A dialect option may be embedded in a source file in form of a dialect
+    tag, a specially formatted comment that specifies a dialect option.
+
+    Dialect Tag EBNF:
+
+    dialectTag :
+        OpeningCommentDelim Prefix dialectOption ClosingCommentDelim ;
+
+    dialectOption :
+        'm2pim' | 'm2iso' | 'm2r10' | 'objm2' |
+        'm2iso+aglet' | 'm2pim+gm2' | 'm2iso+p1' | 'm2iso+xds' ;
+
+    Prefix : '!' ;
+
+    OpeningCommentDelim : '(*' ;
+
+    ClosingCommentDelim : '*)' ;
+
+    No whitespace is permitted between the tokens of a dialect tag.
+
+    In the event that a source file contains multiple dialect tags, the first
+    tag that contains a valid dialect option will be used and any subsequent
+    dialect tags will be ignored.  Ideally, a dialect tag should be placed
+    at the beginning of a source file.
+
+    An embedded dialect tag overrides a dialect option set via command line.
+
+    Examples:
+
+    `(*!m2r10*) DEFINITION MODULE Foobar; ...`
+        Use Modula2 R10 dialect to render this source file.
+    `(*!m2pim+gm2*) DEFINITION MODULE Bazbam; ...`
+        Use PIM dialect with GNU extensions to render this source file.
+
+
+    Algol Publication Mode:
+
+    In Algol publication mode, source text is rendered for publication of
+    algorithms in scientific papers and academic texts, following the format
+    of the Revised Algol-60 Language Report.  It is activated by passing
+    one of two corresponding styles as an option:
+
+    `algol`
+        render reserved words lowercase underline boldface
+        and builtins lowercase boldface italic
+    `algol_nu`
+        render reserved words lowercase boldface (no underlining)
+        and builtins lowercase boldface italic
+
+    The lexer automatically performs the required lowercase conversion when
+    this mode is activated.
+
+    Example:
+
+    `$ pygmentize -O full,style=algol -f latex -o /path/to/output /path/to/input`
+        Render input file in Algol publication mode to LaTeX output.
+
+
+    Rendering Mode of First Class ADT Identifiers:
+
+    The rendering of standard library first class ADT identifiers is controlled
+    by option flag "treat_stdlib_adts_as_builtins".
+
+    When this option is turned on, standard library ADT identifiers are rendered
+    as builtins.  When it is turned off, they are rendered as ordinary library
+    identifiers.
+
+    `treat_stdlib_adts_as_builtins` (default: On)
+
+    The option is useful for dialects that support ADTs as first class objects
+    and provide ADTs in the standard library that would otherwise be built-in.
+
+    At present, only Modula-2 R10 supports library ADTs as first class objects
+    and therefore, no ADT identifiers are defined for any other dialects.
+
+    Example:
+
+    `$ pygmentize -O full,dialect=m2r10,treat_stdlib_adts_as_builtins=Off ...`
+        Render standard library ADTs as ordinary library types.

+    Algol publication style.
+
+    This style renders source code for publication of algorithms in
+    scientific papers and academic texts, where its format is frequently used.
+
+    It is based on the style of the revised Algol-60 language report[1].
+
+    o  No colours, only black, white and shades of grey are used.
+    o  Keywords are rendered in lowercase underline boldface.
+    o  Builtins are rendered in lowercase boldface italic.
+    o  Docstrings and pragmas are rendered in dark grey boldface.
+    o  Library identifiers are rendered in dark grey boldface italic.
+    o  Comments are rendered in grey italic.
+
+    To render keywords without underlining, refer to the `Algol_Nu` style.
+
+    For lowercase conversion of keywords and builtins in languages where
+    these are not or might not be lowercase, a supporting lexer is required.
+    The Algol and Modula-2 lexers automatically convert to lowercase whenever
+    this style is selected.
