 # libffcall
 
+This is a collection of four libraries which can be used to build foreign function call interfaces in embedded interpreters.
+
+The four packages are:
+avcall - calling C functions with variable arguments
+vacall - C functions accepting variable argument prototypes
+trampoline - closures as first-class C functions
+callback - closures with variable arguments as first-class C functions (a reentrant combination of vacall and trampoline)
