+=== Formatting of Individual Sequences ===
+
+!BioRuby can format molecular sequences in a variety of formats.
+Individual sequences can be formatted to (e.g.) Genbank format as shown in the following examples.
+
+For Sequence objects:
+{{{
+seq.to_seq.output(:genbank)
+}}}
+
+For Bio::!FlatFile entries:
+{{{
+entry.to_biosequence.output(:genbank)
+}}}
+
+The following symbols determine the output format:
+ * `:genbank` for Genbank
+ * `:embl` for EMBL
+ * `:fasta` for FASTA
+ * `:fasta_ncbi` for NCBI-type FASTA
+ * `:raw` for raw sequence
+ * `:fastq` for FASTQ (includes quality scores)
+ * `:fastq_sanger` for Sanger-type FASTQ
+ * `:fastq_solexa` for Solexa-type FASTQ
+ * `:fastq_illumina` for Illumina-type FASTQ
