## libmdbx = { Revised and extended descendant of Symas LMDB. }

##
## Libmdbx is superior to LMDB in terms of features and reliability,
## not inferior in performance. libmdbx works on Linux, FreeBSD, MacOS X
## and other systems compliant with POSIX.1-2008, but also support Windows
## as a complementary platform.
##
## The next version is under active non-public development and will be
## released as MithrilDB and libmithrildb for libraries & packages.
## Admittedly mythical Mithril is resembling silver but being stronger and
## lighter than steel. Therefore MithrilDB is rightly relevant name.
##
## MithrilDB will be radically different from libmdbx by the new database
## format and API based on C++17, as well as the Apache 2.0 License.
## The goal of this revolution is to provide a clearer and robust API,
## add more features and new valuable properties of database.
##
## The Future will (be) Positive. Всё будет хорошо.
