+In this tutorial, we write an Alphabets (or Alpha, for now the two are synonymous) program, starting from a mathematical equation for LU decomposition.  Then we will generate code to execute the alphabets program, and test the generated code for correctness.
 The equation for LU Decomposition, derived from first principles using simple algebra in {{:foundations.pdf|Foundations}} (pg.3), is as follows:

 ====Step 2 : Variable Declarations====
-In most cases, a computation uses some inputs and produces outputs. Such variables must be declared with a name, a data type, and a shape/size.  In Alphabets, the shape/size is represented with polyhedral domains.
+In most cases, a computation uses some inputs and produces outputs. Such variables must be declared with a name, a data type, and a shape/size.  In Alpha, the shape/size is represented with polyhedral domains.
 For this example, the ''A'' matrix is given, and we are computing two triangular matrices ''L'' and ''U''. ''A'' is an NxN square matrix.  The declaration for ''A'' looks as follows:
