## TITLE: recolor.sh
##
## DESCRIPTION:  Replaces Colors in the SVG files of an icon
##               theme, does so calling a function after 
##               entering each subdirectory of the icon theme
##               likely needs to be adapted for other icon themes
##               and definitely for other color schemes
