" 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 Dieudonné, Alexander Wagner, Roman Bertle, Charles Rendleman,
" Andrew Griffiths, Joe Krahn, Hendrik Merx, Matt Thompson, Jan Hermann,
" Stefano Zaghi, Vishnu V. Krishnan, Judicaël Grasset, Takuma Yoshida,
" Eisuke Kawashima, and André Chalella.`
