Original commit message from CVS: More Docs updates. Added plugin documentation. I fear we need a gstdoc implementation that loads plugins and does introspection on them. I think we should automatically create the docs for the pads and mime types the plugins provide. Does anyone have enough perl knowledge to add these features? I allready changed the C code to output the pad definitions but my perl knowledge is too limited, for now, to implement the rest of the needed functionality...

# Script : gtkdoc-mktmpl
|
|
# Description : This creates or updates the template files which contain the
|
|
# manually-edited documentation. (A 'template' is a simple text
|
|
# form which is filled in with the description of a function,
|
|
# macro, enum, or struct. For functions and macros it also
|
|
# contains fields for describing the parameters.)
|
|
#
|
|
# This script reads in the existing templates, found in
|
|
# tmpl/*.sgml, moves these files to tmpl/*.sgml.bak, and then
|
|
# recreates the .sgml files according to the structure given in
|
|
# the file $MODULE-sections.txt.
|
|
#
|
|
# Any new templates added, or new function parameters, are
|
|
# marked with 'FIXME' so you can do a grep to see which parts
|
|
# need updating.
|
|
#
|
|
# Any templates which are no longer used (i.e. they are remove
|
|
# from $MODULE-sections.txt) are placed in the file
|
|
# tmpl/$MODULE-unused.txt. If they are included again later
|
|
# they are automatically copied back into position.
|
|
# If you are certain that these templates will never be used
|
|
# again you can delete them from $MODULE-unused.txt.
|
|
#
|
|
# Any parameters to functions which are no longer used are
|
|
# separated from the rest of the parameters with the line
|
|
# '<!-- # Unused Parameters # -->'. It may be that the parameter
|
|
# name has just been changed, in which case you can copy the
|
|
# description to the parameter with the new name. You can delete
|
|
# the unused parameter descriptions when no longer needed.
