## Title-
##       setupSDL
##
## Purpose-
##       Initialize SDL (Software Development Lab) PATH
##
## Last change date-
##       2024/03/28
##
## Usage-
##       . setupSDL
##
## Implementation note-
##       $SDL_ROOT is only used by Makefiles, but
##       $PATH (including ./bat and ./bin) is generally needed.
##         './bat' is useful, but can be omitted.
##         './bin' (initialized by 'make install') is needed:
##            'filecomp' is needed for regression output testing.
##            'makeproj' is used in Makefiles to build dependency files.
