The LaTeX Equation Compiler is a preprocessor for LaTeX files that enables
numeric calculations. It reads equations specified by special keywords in
the LaTeX file and uses them to calculate the numeric value of variables.
Quite a few symbolic calculation capabilities are implemented, for example,
adding an expression to an equation. EQC makes use of the GiNaC library.
