this is read :: "if USE="sdl" then depend on media-libs/libsdl"

Nope, first it checks "do we want SDL support?" then it adds the
dependency if that's the case.

this can be read:
if sdl is in use then :: 
   myconf="$myconf --with-sdl --with-sdl-prefix=/usr"
else
  myconf="$myconf --without-sdl --disable-sdltest"
fi 

because: "use sdl" returns either true (sdl in USE variable) or false
(sdl not in USE variable)

this is standard bash syntax, and can be tested with the following ::

true && echo "it came out true" || echo "it came out false" 
false && echo "it came out true" || echo "it came out false"

nop, the DEPEND line is the only part that acutally makes a dependency,
the rest is compilation depending on how the USE variable is set.

this week it should be..... (next week, whatnotl.)
