-# bpf: a Zig BPF library
-
-This library aims to provide similar functionality as libbpf but leveraging the
-zig programming language. Probes writen in either library should be able to be
-loaded by the other.
-
-# Roadmap
-
-stdlib work:
-- document all map types
-- document all cmd types
-- document all program and attach types
-- zigify cmds
-	- determine all possible errnos
-- zigify bpf helpers (include documentation)
-- get layout for members of structs found in bpf helpers
-
-this lib work:
-- determine how section naming translates into program types and events
-- typify section naming
-- figure out btf and map relocations
-- typify maps
-- @Type(.Struct) object
+# WIP eBPF Package for Zig
