Hello Manuel,

> - floatflt: Other non-Debian licenses
> (I didn't check further.)

According to that:
Today I recognized that the package "ltablex" is in TeX-Live, but
AFAIR in 2007 a read that this package is _not_ free and since
this time I use longtable,tabularx in conjunction with filecontenst and
ltxtable to have longtables with \textwidth, independent to the content.
How can it be that a non free package is included in TeX-Live?
Or is this a misstake of me? Changed the licence type of ltable?
