/* Read the documentation file with name IN_FNAME, perform substitutions

|

Hooks defined with DEFHOOK / DEFHOOKPOD are emitted at the place of a
|
||||
matching @hook in the input file; if there is no matching @hook, the
|
||||
hook is emitted after the hook that precedes it in target.def .
|
||||
Usually, the emitted hook documentation starts with the hook
|
||||
signature, followed by the string from the doc field.
|
||||
The documentation is bracketed in @deftypefn / @deftypevr and a matching
|
||||
@end.
|
||||
While emitting the doc field, @Fcode is translated to @code, and an
|
||||
@findex entry is added to the affected paragraph.
|
||||
If the doc field starts with '*', the leading '*' is stripped, and the doc
|
||||
field is otherwise emitted unaltered; no function signature/
|
||||
@deftypefn/deftypevr/@end is emitted.
|
||||
In particular, a doc field of "*" means not to emit any ocumentation for
|
||||
this target.def / hook_array entry at all (there might be documentation
|
||||
for this hook in the file named IN_FNAME, though).
|
||||
A doc field of 0 is used to append the hook signature after the previous
|
||||
hook's signture, so that one description can be used for a group of hooks.
|
||||
When the doc field is "", @deftypefn/@deftypevr and the hook signature
|
||||
is emitted, but not the matching @end. This allows all the free-form
|
||||
documentation to be placed in IN_FNAME, to work around GPL/GFDL
|
||||
licensing incompatibility issues. */
