# python script to process makedoc instructions in a source file and produce
|
|
# DocBook XML output
|
|
#
|
|
|
|
#
|
|
# This performs 3 stages of processing on it's input, in a similar fashion
|
|
# to makedoc:
|
|
#
|
|
# 1. Discard everything outside of /* */ comments
|
|
# 2. Identify lines which contains commands (a single uppercase word)
|
|
# 3. Apply each command to the text of the following lines (up to the next
|
|
# command or the end of the comment block), to produce some output
|
|
#
|
|
# The resulting output contains one or more DocBook XML refentry elements.
|
|
#
|
|
# To make the output a valid XML document which can be xincluded, those refentry
|
|
# elements are contained by a refcontainer element. refcontainer is not part of
|
|
# the DocBook DTD and should be removed by a suitable XSLT.
