- * Parse and create Jalview Features files Detects GFF format features files and

- * for the features annotation - this normally works on an exact match.
+ * Parses and writes features files, which may be in Jalview, GFF2 or GFF3
+ * format. These are tab-delimited formats but with differences in the use of
+ * columns.
+ *
+ * A Jalview feature file may define feature colours and then declare that the
+ * remainder of the file is in GFF format with the line 'GFF'.
+ *
+ * GFF3 files may include alignment mappings for features, which Jalview will
+ * attempt to model, and may include sequence data following a ##FASTA line.
