-## Compiling with optimizations
-
-CMake is used during compilation to determine which of the following optimization options are enabled. You can set the following nim compiler flags to 0 or 1 to override them:
- - fdatasync from <unistd.h> `--passC:-DHAVE_FDATASYNC=1`
- - F_FULLSYNC from <fcntl.h> `--passC:-DHAVE_FULLFSYNC=1`
- - O_CLOEXEC from <fcntl.h> `--passC:-DHAVE_O_CLOEXEC=1`
- - crc32c from <crc32c/crc32c.h> `--passC:-DHAVE_CRC32C=1`
- - snappy from <snappy.h> `--passC:-DHAVE_SNAPPY=1`
- - zstd from <zstd.h> `--passC:-DHAVE_ZSTD=1`
-
-## Updating
-
-When you want to update this library to a new version of LevelDB, follow these steps:
-- Update LevelDB submodule to new version.
-- Run 'build.sh'.
-- Run 'nimble build' and 'nimble test'.
-- Make sure everything's working.
-- Increment version of this library in 'leveldbstatic.nimble'.
-- Commit the changes.
-- Tag the commit with the new version number.
-- Push.
