-XML-based format is used to keep integrity checksums for files. It is
-well supported format by various tools and it is capable of storing
-multiple checksums simultaneously. That allows us to keep both Streebog
-hashes and much more faster ones.
+.hashes files contain "name hex(hash)" lines with various file checksums.
 
 Nothing prevents you from extending it with additional files, for
 example holding cryptographic signatures.
