+ * Task template system:
+ * templates are rules for a specific test, used to create a "task" that
+ * is executed with those set of rules (arguments, and what not). Tests
+ * that don't have a template with them cannot become tasks, since without
+ * the information for that test there is no way to properly "test" them.
+ * Rules for these templates are described in a template file, using a
+ * task template language.
+ *
+ * The language is a basic finite statemachine, top-down single-line
+ * description language.
+ *
+ * The languge is composed entierly of "tags" which describe a string of
+ * text for a task. Think of it much like a configuration file. Except
+ * it's been designed to allow flexibility and future support for prodecual
+ * semantics.
+ *
+ * The following "tags" are suported by the language
+ *
+ * D:
+ * Used to set a description of the current test, this must be
+ * provided, this tag is NOT optional.
+ *
+ * F:
+ * Used to set a failure message, this message will be displayed
+ * if the test fails, this tag is optional
+ *
+ * S:
+ * Used to set a success message, this message will be displayed
+ * if the test succeeds, this tag is optional.
+ *
+ * T:
+ * Used to set the procedure for the given task, there are two
+ * options for this:
+ * -compile
+ * This simply performs compilation only
+ * -execute
+ * This will perform compilation and execution
+ *
+ * This must be provided, this tag is NOT optional.
+ *
+ * C:
+ * Used to set the compilation flags for the given task, this
+ * must be provided, this tag is NOT optional.
+ *
+ * E:
+ * Used to set the execution flags for the given task. This tag
+ * must be provided if T == -execute, otherwise it's erroneous
+ * as compilation only takes place.
+ *
+ * M:
+ * Used to describe a string of text that should be matched from
+ * the output of executing the task. If this doesn't match the
+ * task fails. This tag must be provided if T == -execute, otherwise
+ * it's erroneous as compilation only takes place.
+ *
+ * I:
+ * Used to specify the INPUT source file to operate on, this must be
+ * provided, this tag is NOT optional
+ *
+ *
+ * Notes:
+ * These tags have one-time use, using them more than once will result
+ * in template compilation errors.
+ *
+ * Lines beginning with # or // in the template file are comments and
+ * are ignored by the template parser.
+ *
+ * Whitespace is optional, with exception to the colon ':' between the
+ * tag and it's assignment value/
+ *
+ * The template compiler will detect erronrous tags (optional tags
+ * that need not be set), as well as missing tags, and error accordingly
+ * this will result in the task failing.
