DMD uses different linkers depending on the platform. For the 
compiler, -L means 'pass this command to the linker.' In this 
case, that just also happens to be -L, which is understood by ld 
(the system linker) as the flag to set the library path. If you 
were using the Microsoft linker on Windows, it would be 
-L/LIBPATH:dir. If you were manually linking with libevent on Mac 
or Linux, you would pass -L-levent, and so on.
