-$ Comment line starts with dollar sign and white space.
-$ 
-$ $program <name> starts a new test program section called <name>. Contains all other sections.
-$ 
-$ $attrib <name> starts vertex data input section for attrib called <name>. Each line consists of
-$   four values that form single vertex attrib.
-$ 
-$ $vertex starts vertex shader section. Contains $code and &output sections.
-$ 
-$ $code starts source code section. All text in this section gets compiled into appropriate
-$   shader object.
-$ 
-$ $output starts shader execution results section. These are compared, value-by-value,
-$   with results of executing printMESA() functions within a shader.
