df2fba9e | 22 | /* The syntax of gfortran modules resembles that of lisp lists, i.e. a |
6de9cd9a DN |
23 | sequence of atoms, which can be left or right parenthesis, names, |
24 | integers or strings. Parenthesis are always matched which allows | |
25 | us to skip over sections at high speed without having to know | |
26 | anything about the internal structure of the lists. A "name" is | |
27 | usually a fortran 95 identifier, but can also start with '@' in | |
28 | order to reference a hidden symbol. | |
29 | ||
30 | The first line of a module is an informational message about what | |
31 | created the module, the file it came from and when it was created. | |
32 | The second line is a warning for people not to edit the module. | |
33 | The rest of the module looks like: | |
