NOTES:

* Whitespace is not allowed between symbols unless otherwise noted.
* Character symbols are defined with Perl style character classes.
* A multi-line field may not contain any lines that consist of a single period followed by a newline, as this is reserved for terminating the multi-line field.
* Modeled on Celera Assembler 3-code format: "A Whole-Genome Assembly of Drosophila." Myers E, Sutton G, et. al., Science, 2000. 287(5461):2196-204.
