By default, Yaffs2 code stores a so-called summary at the end of each block. These summaries are arrays containing the useful parts of the tags for the chunks in a given block. Storing tag data in such a condensed form enables retrieving all the tags for a given block in a single read.
Summaries are merely a performance optimization and maintaining them requires extra storage space. Add a new command-line option, -S, which prevents summaries from being written, saving some storage space at the cost of slower file system scanning. Update README.md accordingly.
