To read 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 read files in bzip2 format. (Both of
these are the default configurations for libSBML.) Errors about unreadable
files will be logged if a compressed filename is given and libSBML was
not linked with the corresponding required library.
