Code name: base64
Marvin is able to import and export Base64 encoded files (RFC 1341). A binary file is encoded as a multiline ASCII file containing the characters `a'-`z', `A'-`Z', `0'-`9', `+' and `/'. A line contains no more than 76 characters. 3 input bytes are encoded in the form of 4 ASCII characters. At the end of the file, there might be one or two `=' characters, for padding.
At export, the molecule file format is specified as an export option. Example:
base64:gzip:sdf Exports a base64 encoded gzipped SDfile.
