# Updates the Doxygen generated documentation files in the source tree.
# If the doxygen command is not installed, it will exit with an error.
# This script can generate Doxygen documentation for all source files or for
# just liblzma API header files.
#
# It is recommended to use this script to update the Doxygen-generated HTML
# files since this will include the package version in the output and,
# in case of liblzma API docs, strip JavaScript files from the output.
