# Unix Installation:
#   Makefile.PL should find the necessary path information from 
#   allegro-config.
#
# Win32 Installation:
#   It is assumed Allegro is installed in the standard directories and 
#   will not need any -I or -L options to compile.  Change $libs and 
#   $inc below if this is not the case.
#
#   Setting STATICLINK=1 in the environment will build without a 
#   dependency on alleg4x.dll.
