   5 # Updates the Doxygen generated documentation files in the source tree.
   6 # If the doxygen command is not installed, it will exit with an error.
   7 # This script can generate Doxygen documentation for all source files or for
   8 # just liblzma API header files.
   9 #
  10 # It is recommended to use this script to update the Doxygen-generated HTML
  11 # files since this will include the package version in the output and,
  12 # in case of liblzma API docs, strip JavaScript files from the output.
