" Vim syntax file
" Language: Fortran 2023 (and Fortran 2018, 2008, 2003, 95, 90, and 77)
" Version: (v113) 2024 February 01
" Maintainers: Ajit J. Thakkar <ajit@unb.ca>; <https://ajit.ext.unb.ca/>
" Joshua Hollett <j.hollett@uwinnipeg.ca>
" Usage: For instructions, do :help fortran-syntax from Vim
" Credits:
" Version 0.1 for Fortran 95 was created in April 2000 by Ajit Thakkar from an
" older Fortran 77 syntax file by Mario Eusebio and Preben Guldberg.
" Since then, useful suggestions and contributions have been made, in order, by:
" Andrej Panjkov, Bram Moolenaar, Thomas Olsen, Michael Sternberg, Christian Reile,
" Walter Dieudonne, Alexander Wagner, Roman Bertle, Charles Rendleman,
" Andrew Griffiths, Joe Krahn, Hendrik Merx, Matt Thompson, Jan Hermann,
" Stefano Zaghi, Vishnu V. Krishnan, Judicael Grasset, Takuma Yoshida,
" Eisuke Kawashima, Andre Chalella, Fritz Reese, Karl D. Hammond,
" and Michele Esposito Marzino.
