+**What it does**
+
+This tool re-formats a FASTA file, changing the width of the nucleotides lines.
+  
+**TIP:** Outputting a single line (with **width = 0**) can be useful for scripting (with **grep**, **awk**, and **perl**). Every odd line is a sequence identifier, and every even line is a nucleotides line.
+
+--------
+
+**Example**
+
+Input FASTA file (each nucleotides line is 50 characters long)::
