The package "PyFIT" is no longer found via "Package list" or "Package search" functionality.
NOTE: Different package version were formerly registered under "PyFIT" and "PyFit".
This problem exists approx. for 1 year.
Normally, I only tried to search for this package.
But yesterday, I used a stored URL and finally had access to the package again.
Therefore, I assume that the generation of "package list" and "package search index"
was changed, somehow neglecting the "existing" package.
