----------------------------------------------------------------------
This package implements new commands to go within
the first argument of \ifthenelse to test whether
a string is void or not, if a command is defined
or equivalent to another. It includes also the
possibility to make use of the complex expressions
introduced by the package calc, together with the
ability of defining new commands to handle complex
tests. This package requires the e-TEX features.
