+ASN1 BER Encoding / Decoding Library for the GO programming language.
+---------------------------------------------------------------------
+
+Required libraries: 
+   None
+
+Working:
+   Very basic encoding / decoding needed for LDAP protocol
+
+Tests Implemented:
+   A few
+
+TODO:
+   Fix all encoding / decoding to conform to ASN1 BER spec
+   Implement Tests / Benchmarks
