+ "hungrycat prints the contents of a file to standard output, while
+simultaneously freeing the disk space it occupied. It is useful if you need
+to process a large file, don't have enough space to store both the input and
+output files, and don't need the input file afterwards.
+While similar in principle to running @command{cat} immediately followed by
+@command{rm}, @command{hungrycat} actually frees blocks as soon as they are
+printed instead of after the entire file has been read, which is often too
+late.")
