Importer for gzipped (.gz) files of already supported formats. With the help of this importer, you can open, for example, *.pdb.gz files directly in SAMSON - they will be decompressed and then a proper importer for the file's format will be used.

For the decompression, the zlib library (v. 1.2.11) written by Jean-loup Gailly and Mark Adler is used.
