     Object of class 'data.frame'. GFF is a file format for annotating
     genomes, see <insert the URL to the documentation page for GFF at
     Sanger here>. The format is essentially a rectangular table, and
     here it is represented as a data frame.

     Two GFF files were downloaded: 'saccharomyces_cerevisiae.gff' from
     'ftp://genome-ftp.stanford.edu/pub/yeast/data_download/chromosomal_feature'
     on 7 Aug 2005, 18:16 BST, and 'IGR_v24.2.p001.allowoverlap.GFF'
     from 'http://jura.wi.mit.edu/fraenkel/download/release_v24/GFF'
     upon suggestion from the SGD curators on 30 Aug 2005. (Future
     versions of SGD's GFF files are likely to include the latter as
     well). They were parsed, combined and written into the 'gff'
     data.frame with the script 'makeProbeAnno.R' in the 'inst/scripts'
     directory of this package.
