+%
+% PURPOSE:   Improve float mechanism and baselineskip settings 
+%
+% SHORT DESCRIPTION:
+%
+% (It is rewritten version of stkernel package)
+%
+% Provides new commands:
+%
+% \dblfloatsatbottom, \dblfloatsattop (removed!)
+% -----------------------------------
+%    Use instead optional parameters [b] and [t] 
+%    for dblfloat environments (default = [tbp]).
+%
+% \fnbelowfloat
+% -------------
+%    Puts footnotes below the bottom floats
+%
+% \fnunderfloat (default and standard)
+% -------------
+%    Puts footnotes under the bottom floats
+%
+% \setbaselinefloat
+% -----------------
+%    Allows baselineskip to stretch and shrink if \baselineskip
+%    is set with command \@setfontsize.
+%    Example: \@setfontsize\normalsize\@xpt{12pt plus .1pt minus .1pt}%
+%
+% \setbaselinefixed (default and standard)
+%    Disables baselineskip to stretch and shrink even if \baselineskip
+%    is set with command \@setfontsize.
+%    Example: \@setfontsize\normalsize\@xpt{12pt plus .1pt minus .1pt}%
+%
+% Allows to use optional parameters [t] or [b] for dblfloats.
