\newif\iflefttorightcolumns
\lefttorightcolumnstrue
Define options that set the direction:
\DeclareOptionX{LR}{\lefttorightcolumnstrue}
\DeclareOptionX{RL}{\lefttorightcolumnsfalse}
If the \normalcolor command is something other than \relax, then implement
the color=true option as the default, otherwise implement the color=false
option as the default.
\ifx\normalcolor\relax
\@ff@disablecolor
\else
\@ff@enablecolor
\fi
Now the defaults have all been set, the package options specified by the user
can be processed:
\ProcessOptionsX
If color=true option has been specified, but no color package has been loaded
yet, load color.sty
\ifx\normalcolor\relax
\ifthenelse{\equal{\flowframetextcol}{}}%
