%description
Package 'runonce' helps automating the saving of long-running code to help
running the same code multiple times. If you run some long-running code
once, it saves the result in a file on disk. Then, if the result already
exists, i.e. if the code has already been run and its output has already
been saved, it just reads the result from the stored file instead of
running the code again.
