33 # Biopieces are command line scripts and uses OptionParser to parse command line
34 # options according to a list of casts. Each cast prescribes the long and short
35 # name of the option, the type, if it is mandatory, the default value, and allowed
36 # and disallowed values. An optional list of extra casts can be supplied, and the
37 # integrity of the casts are checked. Following the command line parsing, the
38 # options are checked according to the casts. Methods are also included for handling
39 # the parsing and emitting of Biopiece records, which are ASCII text records consisting
40 # of lines with a key/value pair separated by a colon and a white space ': '.
41 # Each record is separated by a line with three dashes '---'.
