+== Structure of Tuning Specifications ==
+
+The tuning specifications of Orio simply consist of a sequence of ''definition statements''. Every definition statement contains a series of ''auxiliary statements'', which can be categorized into four different types:
+
+ 1. ''argument statement''
+ 1. ''let statement''
+ 1. ''parameter statement''
+ 1. ''constraint statement''
+ 1. ''declaration statement''
+
+Argument statement is used to collect specific information from the Orio user about the pertinent tuning components. One example is the `command` argument (in the `build` definition) that is used to indicate the compilation command. 
+
+
+The main use of a let statement is to store a temporary data into a variable that may be reused multiple times by other successive statements. 
+
+The purpose of parameter statement is to assign a range of values to the tuning parameters, which can be either performance parameters or input problem parameters.
