/*
* 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.
*
* 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
* -fail
* This will perform compilation, but requires
* the compilation to fail in order to succeed.
*
* 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.
*
* F: Used to set some test suite flags, currently the only option
* is -no-defs (to including of defs.qh)
*
* 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.
