This package provides alternative styles that allow compressed file I/O via compression libraries. This is similar to what is enabled through using the -DLAMMPS_GZIP preprocessor flag, but it does not open a pipe to an external executable that handles the compression. These styles use library calls to libraries like zlib instead and thus have to be compiled using the library header files and linked to the respective library. This provides an alternative for compressed file I/O on systems where using a pipe can cause problems, e.g. when using RDMA communication with pinned memory like clusters with infiniband or myrinet.

At the moment a few selected dump styles are supported for writing via this packaging.
