|
|
# Each block contains a list of markers, each one can be followed by
|
|
# some arbitrary text or a list of fields. Here's an example:
|
|
#
|
|
# <Struct>
|
|
# MyStruct
|
|
#
|
|
# <Description>
|
|
# this structure holds some data
|
|
#
|
|
# <Fields>
|
|
# x :: horizontal coordinate
|
|
# y :: vertical coordinate
|
|
#
|
|
#
|
|
# This example defines three markers: 'Struct', 'Description' & 'Fields'
|
|
# The first two markers contain arbitrary text, while the last one contains
|
|
# a list of field
|
|
#
|
|
# each field is simple of the format: WORD :: TEXT....
|
|
#
|
|
# Note that typically, each comment block is followed by some source
|
|
# code declaration that may need to be kept in the reference..
|
|
#
|
|
# Note that markers can alternatively be written as "@MARKER:"
|
|
# instead of "<MAKRER>". All marker identifiers are converted to
|
|
# lower case during parsing, in order to simply sorting..
|
|
#
|
|
# We associate with each block the following source lines that do not
|
|
# begin with a comment. For example, the following:
|
|
#
|
|
# /**********************************
|
|
# *
|
|
# * <mytag> blabla
|
|
# *
|

|
# the "blabla" block
|
|
#
|
|
# However, the comment will be kept, with following source lines
|
|
# if it contains a starting '#' or '@' as in:
|
|
#
|
|
# /*@.....*/
|
