|

|
||

|
||
# /**************************/
|
||
#
|
||
# 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 fields.
|
||
#
|
||
# 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 "<MARKER>". 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
|
||
# *
|
||
# */

# bla_bla_bla
|
||
# bilip_bilip

# /* - this comment acts as a separator - */
|
||
#
|
||
# blo_blo_blo
|
||
#
|
||
#
|
||
# will only keep the first two lines of sources with
|
||
# the "blabla" block.
|
||
#
|
||
# However, the comment will be kept, with following source lines
|
||
# if it contains a starting '#' or '@' as in:
|
||
#
|
||
# /*@.....*/
|

# /*#.....*/
