+     "This is a package for parsing Affymetrix files (CDF, CEL, CHP, BPMAP,
+BAR).  It provides methods for fast and memory efficient parsing of Affymetrix
+files using the Affymetrix' Fusion SDK.  Both ASCII- and binary-based files
+are supported.  Currently, there are methods for reading @dfn{chip definition
+file} (CDF) and a @dfn{cell intensity file} (CEL).  These files can be read
+either in full or in part.  For example, probe signals from a few probesets
+can be extracted very quickly from a set of CEL files into a convenient list
+structure.")
