     A tiny library that make the interaction with the |babel| package easier.
     Despite the name, it may also be useful in other contexts, namely whenever
     the catcodes of important symbols are changed globally. Normally, using
     this library is always a good idea; it is not always loaded by default
     since in some rare cases it may break old code.

 The problems this library tries to fix have to do with the so-called
 ``catcodes'' of symbols used inside \tikzname. In normal \TeX\ operation,
