xifthen – Extended conditional commands
This package extends the ifthen
implementing 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. The package also
enables use of complex expressions as introduced by the package
calc, together with the ability of
defining new commands to handle complex tests.
The package requires e-TeX features.
