To write a gzip/zip file, libSBML needs to be configured and linked with
the zlib library at
compile time. It also needs to be linked with the bzip2 library to write files in bzip2 format. (Both
of these are the default configurations for libSBML.) Errors about
unreadable files will be logged and this method will return
false
if a compressed filename is given and libSBML was
not linked with the corresponding required library.
