;;; Commentary:
+
;; Smart mode for editing F90 programs in FREE FORMAT.
;; Knows about continuation lines, named structured statements, and other
;; new features in F90 including HPF (High Performance Fortran) structures.
;; There are two separate features for highlighting the code.
;; 1) Upcasing or capitalizing of all keywords.
-;; 2) Different colors/fonts for different structures. (X-windows)
-;; (using either font-lock-mode or hilit19)
+;; 2) Colors/fonts using font-lock-mode. (only when using X-windows)
;; Automatic upcase of downcase of keywords is controlled by the parameter
;; f90-auto-keyword-case.
-;; To use hilit19 it must be loaded before this file. Then the parameter
-;; f90-auto-hilit19 determines if each line should be updated automatically.
;; The indentations of lines starting with ! is determined by the first of the
-;; following matches:
-;; start-string indent variable holding start-string
-;; !!! 0
-;; !hpf$ 0 f90-directive-comment (default nil)
-;; !!$ 0 f90-comment-region (default !!$)
-;; ! as code f90-indented-comment (a regexp, default !)
-;; default comment-column
-;; Ex: Here is the result of three different settings of f90-indented-comment
-;; f90-indented-comment !-indentation !!-indentation
-;; ! as code as code
-;; !! comment-column as code
-;; ![^!] as code comment-column
+;; following matches (the values in the left column are the default values):
+
+;; start-string/regexp indent variable holding start-string/regexp
+;; !!! 0
+;; !hpf\\$ (re) 0 f90-directive-comment-re
+;; !!$ 0 f90-comment-region
+;; ! (re) as code f90-indented-comment-re
+;; default comment-column
+
+;; Ex: Here is the result of 3 different settings of f90-indented-comment-re
+;; f90-indented-comment-re !-indentation !!-indentation
+;; ! as code as code
+;; !! comment-column as code
+;; ![^!] as code comment-column
;; Trailing comments are indented to comment-column with indent-for-comment M-;
;; f90-comment-region (C-c;) toggles insertion of f90-comment-region in region.

+;; (turn-on-font-lock) ; for highlighting
+;; (f90-add-imenu-menu) ; extra menu with functions etc.
;; (if f90-auto-keyword-case ; change case of all keywords on startup
;; (f90-change-keywords f90-auto-keyword-case))
;; ))
;; in your .emacs file (the shown values are the defaults). You can also
;; change the values of the lists f90-keywords etc.
;; The auto-fill and abbreviation minor modes are accessible from the menu,
-;; or by using M-x f90-auto-fill-mode and M-x abbrev-mode, respectively.
+;; or by using M-x auto-fill-mode and M-x abbrev-mode, respectively.
;; Remarks
;; 1) Line numbers are by default left-justified. If f90-leave-line-no is
;; non-nil, the line numbers are never touched.
;; 2) Multi-; statements like > do i=1,20 ; j=j+i ; end do < are not handled
;; correctly, but I imagine them to be rare.
-;; 3) You can use either hilit19 or font-lock-mode for your highlighting
-;; a) To use hilit19, be sure that hilit19 is loaded before this file
-;; b) To use font-lock-mode, nothing special is needed.
+;; 3) Regexps for hilit19 are no longer supported.
;; 4) For FIXED FORMAT code, use the ordinary fortran mode.
;; 5) This mode does not work under emacs-18.x.
+;; 6) Preprocessor directives, i.e., lines starting with # are left-justified
+;; and are untouched by all case-changing commands. There is, at present, no
+;; mechanism for treating multi-line directives (continued by \ ).
+;; 7) f77 do-loops do 10 i=.. ; ; 10 continue are not correctly indented.
+;; You are urged to use f90-do loops (with labels if you wish).
+;; 8) The highlighting mode under XEmacs is not as complete as under Emacs.
