+" Vim syntax file
+" Language:    Modula-2 (ISO)
+" Maintainer:  B.Kowarsch <trijezdci@moc.liamg>
+" Last Change: 2016 August 22
+
+" ----------------------------------------------------
+" THIS FILE IS LICENSED UNDER THE VIM LICENSE
+" see https://github.com/vim/vim/blob/master/LICENSE
+" ----------------------------------------------------
+
+" Remarks:
+" Vim Syntax files are available for the following Modula-2 dialects:
+" * for the PIM dialect : m2pim.vim
+" * for the ISO dialect : m2iso.vim (this file)
+" * for the R10 dialect : m2r10.vim
+
+" -----------------------------------------------------------------------------
+" This syntax description follows ISO standard IS-10514 (aka ISO Modula-2)
+" with the addition of the following language extensions:
+" * non-standard types LONGCARD and LONGBITSET
+" * non-nesting code disabling tags ?< and >? at the start of a line
+" -----------------------------------------------------------------------------
+
+" Parameters:
+"
+" Vim's filetype script recognises Modula-2 dialect tags within the first 200
+" lines of Modula-2 .def and .mod input files.  The script sets filetype and
+" dialect automatically when a valid dialect tag is found in the input file.
+" The dialect tag for the ISO dialect is (*!m2iso*).  It is recommended to put
+" the tag immediately after the module header in the Modula-2 input file.
+"
+" Example:
+"  DEFINITION MODULE Foolib; (*!m2iso*)
+"
+" Variable g:modula2_default_dialect sets the default Modula-2 dialect when the
+" dialect cannot be determined from the contents of the Modula-2 input file:
+" if defined and set to 'm2iso', the default dialect is ISO.
+"
+" Variable g:modula2_iso_allow_lowline controls support for lowline in identifiers:
+" if defined and set to a non-zero value, they are recognised, otherwise not
+"
+" Variable g:modula2_iso_disallow_octals controls the rendering of octal literals:
+" if defined and set to a non-zero value, they are rendered as errors.
+"
+" Variable g:modula2_iso_disallow_synonyms controls the rendering of @, & and ~:
+" if defined and set to a non-zero value, they are rendered as errors.
+"
+" Variables may be defined in Vim startup file .vimrc
+"
+" Examples:
+"  let g:modula2_default_dialect = 'm2iso'
+"  let g:modula2_iso_allow_lowline = 1
+"  let g:modula2_iso_disallow_octals = 1
+"  let g:modula2_iso_disallow_synonyms = 1

+" Vim syntax file
+" Language:    Modula-2 (R10)
+" Maintainer:  B.Kowarsch <trijezdci@moc.liamg>
+" Last Change: 2020 June 18 (moved repository from bb to github)
+
+" ----------------------------------------------------
+" THIS FILE IS LICENSED UNDER THE VIM LICENSE
+" see https://github.com/vim/vim/blob/master/LICENSE
+" ----------------------------------------------------
+
+" Remarks:
+" Vim Syntax files are available for the following Modula-2 dialects:
+" * for the PIM dialect : m2pim.vim
+" * for the ISO dialect : m2iso.vim
+" * for the R10 dialect : m2r10.vim (this file)
+
+" -----------------------------------------------------------------------------
+" This syntax description follows the Modula-2 Revision 2010 language report
+" (Kowarsch and Sutcliffe, 2015) available at http://modula-2.info/m2r10.
+" -----------------------------------------------------------------------------
+
+" Parameters:
+"
+" Vim's filetype script recognises Modula-2 dialect tags within the first 200
+" lines of Modula-2 .def and .mod input files.  The script sets filetype and
+" dialect automatically when a valid dialect tag is found in the input file.
+" The dialect tag for the R10 dialect is (*!m2r10*).  It is recommended to put
+" the tag immediately after the module header in the Modula-2 input file.
+"
+" Example:
+"  DEFINITION MODULE Foolib; (*!m2r10*)
+"
+" Variable g:modula2_default_dialect sets the default Modula-2 dialect when the
+" dialect cannot be determined from the contents of the Modula-2 input file:
+" if defined and set to 'm2r10', the default dialect is R10.
+"
+" Variable g:modula2_r10_allow_lowline controls support for lowline in identifiers:
+" if defined and set to a non-zero value, they are recognised, otherwise not
+"
+" Variables may be defined in Vim startup file .vimrc
+"
+" Examples:
+"  let g:modula2_default_dialect = 'm2r10'
+"  let g:modula2_r10_allow_lowline = 1
