sztool is a simple command-line tool for working with snappy compressed files, similar to the gzip command for gzipped files.
The basic usage for compression is:
sztool -c in out
The basic usage for decompression is:
sztool -d in out
In both cases, in and out are input and output files. These files
can be specified as "-" to use stdin or stdout.
The out parameter can be omitted. For compression(-c), out defaults
to in.sz, where in is the input file. For decompression (-d), out
defaults to stdout.
