# Parameter 1 is the name of the rule. This name is used as variable prefix,

# and the targets generated are listed in a variable by that name. Note that

# the index.html file will work as a "touch file" for all the magnitude of

# files that are generated by javadoc.

#

# Remaining parameters are named arguments. These include:

#   MODULES - Modules to include

#   PACKAGES - Packages to include

#   IS_CORE - Set to TRUE for the Core API package which needs special treatment

#   API_ROOT - Where to base the documentation (jre or jdk)

#   DEST_DIR - A directory relative to the API root

#   OVERVIEW - Path to a html overview file

#   TITLE - Default title to use for the more specific versions below

#   WINDOW_TITLE - Title to use in -windowtitle. Computed from TITLE if empty.

#   HEADER_TITLE - Title to use in -header. Computed from TITLE if empty.

#   DOC_TITLE - Title to use in -doctitle. Computed from TITLE if empty.

#   FIRST_COPYRIGHT_YEAR - First year this bundle was introduced

#   DISABLED_DOCLINT - Doclint warnings to exclude.

#   DOCLINT_PACKAGES - Optional -Xdoclint/package value

#   SPLIT_INDEX - Enable -splitIndex (split index-all.html if it is too large)

#   BOTTOM_COPYRIGHT_URL - Copyright URL to use in -bottom

#   BOTTOM_TEXT - Extra text to use in -bottom
