This is a yet another ASDF extension. It is built by @borodust to distribute a prebuilt C/C++ library wrappers he is making for gamedev.

Here is an example of the system definition which uses "bodge-blobs-support":

(asdf:defsystem chipmunk-blob
  :author "Pavel Korolev"
  :description "Chipmunk physics foreign library collection"
  :license "MIT"
  :defsystem-depends-on (:bodge-blobs-support)
  :class :bodge-blob-system
  :libraries (((:darwin :x86-64) "libchipmunk.dylib.bodged" "x86_64/")
              ((:darwin :x86) "libchipmunk.dylib.bodged" "x86/")
              ((:unix (:not :darwin) :x86-64) "libchipmunk.so.bodged" "x86_64/")
              ((:unix (:not :darwin) :x86) "libchipmunk.so.bodged" "x86/")
              ((:windows :x86-64) "libchipmunk.dll.bodged" "x86_64/")
              ((:windows :x86) "libchipmunk.dll.bodged" "x86/")))

This definition contains a list of libraries which should be loaded by CFFI for different combinations of *features*.

When you load such a system, it automatically sets a path to the library and loads it into the Lisp image:

POFTHEDAY> (ql:quickload :chipmunk-blob)

POFTHEDAY> (bodge-blobs-support:list-registered-libraries)
(#P"/Users/art/poftheday/.qlot/dists/
    quicklisp/software/chipmunk-blob-stable-55c6bf5b-git/
    x86_64/libchipmunk.dylib.bodged")

POFTHEDAY> cffi:*foreign-library-directories*
(#P"/Users/art/poftheday/.qlot/dists/
    quicklisp/software/chipmunk-blob-stable-55c6bf5b-git/x86_64/"
   (CFFI::EXPLODE-PATH-ENVIRONMENT-VARIABLE "LD_LIBRARY_PATH")
   (CFFI::EXPLODE-PATH-ENVIRONMENT-VARIABLE "DYLD_LIBRARY_PATH")
   (UIOP/OS:GETCWD) (CFFI::DARWIN-FALLBACK-LIBRARY-PATH))

POFTHEDAY> (cffi:list-foreign-libraries)
(#<CFFI:FOREIGN-LIBRARY LIBCHIPMUNK.DYLIB.BODGED-743 "libchipmunk.dylib.bodged">
 #<CFFI:FOREIGN-LIBRARY LIBOSICAT "libosicat.dylib">)

As you can see, this way we can easily install a library from the Quicklisp. It will bring all prebuilt binary parts for your system.

This extension can be used not only by gamedev libraries but with any library which needs to interop with C/C++ code via a wrapper.
