# DocMaker is a very simple program used to generate HTML documentation
# from the source files of the FreeType packages.
#
# I should really be using regular expressions to do this, but hey,
# i'm too lazy right now, and the damn thing seems to work :-)

# The FreeType 2 reference is extracted from the source files. These contain
# various comment blocks that follow one of the following formats:
#
#  /**************************
#   *
#   *  FORMAT1
#   *
#   *
#   *
#   *
#   *************************/
#
#  /**************************/
#  /*                        */
#  /*  FORMAT2               */
#  /*                        */
#  /*                        */
#  /*                        */
#  /*                        */
#
#  /**************************/
#  /*                        */
#  /*  FORMAT3               */
#  /*                        */

#  /*                        */
#  /**************************/
#
# 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
#    *
#    */
#
#    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:
#
#     /*@.....*/
#     /*#.....*/
#     /* @.....*/
#     /* #.....*/
