+    *
+    * \ingroup core
+    *
+    * Reads a multifasta sequence file from a string, a stream or a file
+    * and returns a Container. See the description of the format below.
+    * Formats a fasta string from a sequence container object and places
+    * it in a string, a stream of a file. All methods are static and the
+    * class cannot be instantiated. The methods parsef and formatf will
+    * open the file for you while the others will read/write directly
+    * in a string.
+    * 
+    * Specifications of the fasta format:
+    * 
+    *    - The number of sequences is not limited.
+    * 
+    *    - Each sequence is preceded by a header limited to a single
+    *      line and starting by a ">" character.
+    * 
+    *    - The header length is not limited and all characters are
+    *      allowed but white spaces and special characters are
+    *      discouraged.
+    * 
+    *    - Group indices are specified by \@0, \@1, \@2...  strings
+    *      appearing at the end of the header string (just before the
+    *      carriage return). Note that group labels are ignored by
+    *      default.
+    * 
+    *    - Group indices are ignored unless specifically specified in a
+    *      parser's options.
+    * 
+    *    - The sequence itself continues on following lines until the
+    *      next ">" character or the end of the file.
+    * 
+    *    - White spaces, tab and carriage returns are allowed at any
+    *      position There is no limitation in length and different
+    *      sequences can have different lengths.
+    * 
+    *    - Although the standard is lower case characters, Fasta
+    *      assumes upper case characters and only supports lower case
+    *      characters (and converts them to upper case characters).
+    *      Information coded by change in case is lost.
