#D Documentation can be woven into a source file. The next
#D routine generates a new, \TEX\ ready file with the
#D documentation and source fragments properly tagged. The
#D documentation is included as comment:
#D
#D \starttypen
#D %D ......  some kind of documentation
#D %M ......  macros needed for documenation
#D %S B       begin skipping
#D %S E       end skipping
#D \stoptypen
#D
#D The most important tag is \type {%D}. Both \TEX\ and \METAPOST\
#D files use \type{%} as a comment chacacter, while \PERL, \RUBY\
#D and alike use \type{#}. Therefore \type{#D} is also handled.
#D
#D The generated file gets the suffix \type{ted} and is
#D structured as:
#D
#D \starttypen
#D \startmodule[type=suffix]
#D \startdocumentation
#D \stopdocumentation
#D \startdefinition
#D \stopdefinition
#D \stopmodule
#D \stoptypen
#D
#D Macro definitions specific to the documentation are not
#D surrounded by start||stop commands. The suffix specifaction
#D can be overruled at runtime, but defaults to the file
#D extension. This specification can be used for language
#D depended verbatim typesetting.

# This script is used to generate hyphenation pattern files
# that suit ConTeXt. One reason for independent files is that
# over the years too many uncommunicated changes took place
# as well that inconsistency in content, naming, and location
# in the texmf tree takes more time than I'm willing to spend
# on it. Pattern files are normally shipped for LaTeX (and
# partially plain). A side effect of independent files is that
# we can make them encoding independent.
