+TODO
+====
+
+Stuff we didn't finish and where help is needed.  Cleaning up the below
+list is another thing we need help with.
+
+
+- Build with debug memory allocation or dmalloc library
+  - http://dmalloc.com/
+  - https://www.gnu.org/software/automake/manual/html_node/Public-Macros.html (`AM_WITH_DMALLOC`)
+
+- Switch to npcap (win32)
+
+- Take inventory of http://stackoverflow.com/questions/tagged/libnet#
+
+- Add automatic tests for `make check`, IPv6 in particular
+
+- change all `__WIN32` and `__WIN32__` preprocessor directives with the
+  more universal `WIN32` and `_WIN32` directives (msvc + mingw)
+  (eliminating the need for `-mwin32`)
+
+- Improve documentation: FAQ, Examples, adding RFCs
+
+- Fix "broken" samples (on win32?)
+
+- Fix MSVC/Mingw collision
+
+
+1.1.x TODO LIST
+---------------
+
+The following is possibly outdated and already fixed.
+ 
+- Update the man page!
+
+- Add a programmer's man page detailing the pblock architecture.
+
+- Fix plist memory leak.
+
+- Fix IPv6.  According to RFC 2992:
+
+  > "Another difference from IPv4 raw sockets is that complete packets
+  > (that is, IPv6 packets with extension headers) cannot be read or
+  > written using the IPv6 raw sockets API.  Instead, ancillary data
+  > objects are used to transfer the extension headers, as described
+  > later in this document.  Should an application need access to the
+  > complete IPv6 packet, some other technique, such as the datalink
+  > interfaces BPF or DLPI, must be used.
+  >
+  > All fields in the IPv6 header that an application might want to
+  > change (i.e., everything other than the version number) can be
+  > modified using ancillary data and/or socket options by the
+  > application for output.  All fields in a received IPv6 header (other
+  > than the version number and Next Header fields) and all extension
+  > headers are also made available to the application as ancillary data
+  > on input.  Hence there is no need for a socket option similar to the
+  > IPv4 `IP_HDRINCL` socket option."
+
+- Add self-throttling logic to `libnet_write()`/`libnet_init()`?
+  Advanced mode thing?
+
+- Prune the include list in `libnet.h.in`.  Also add conditionals
+  around the headers we use for building the library, but not when
+  using it.
+
+- Data marshalling API for unaligned structures (like STP).
+
+- Make Cisco ISL work.  The issue is that we have build our Ethernet
+  frame first, then encapsulate it inside of an ISL envelope.
+    - We have to compute CRCs for both Ethernet and ISL.
+
+- Tune advanced interface functionality that allow the application
+  programmer to get inside `libnet_t`.
+
+- Test HPUX 11 port.
+
+- Test cywin32 port.
+
+- Flesh out the advanced mode.
+
+- Consider making a flag for "strict mode" where libnet will check
+  things like when you build an IP options list there is an IP
+  header preceding it (likewise for TCP)...  Other "smart" things
+  could happen in this mode too.  When in non-strict mode, libnet
+  will be less rigid but prone to user-error mode.
+
+- If we have a problem building a header we might end up freeing it
+  creating a NULL entry on the list and preventing us from getting to
+  entries beyond it (to free or whatever).  Maybe we should mark it
+  bad or something and rely on the cleanup at the end to free it up?
+
+- Fix checksum support for CDP
+
+- Verify Checksuming:  
+  Currently verified working on OpenBSD/Linux/Solaris:
+  - raw  IP/UDP         [with and without data]
+  - raw  IP/TCP         [with and without data]
+  - raw  IP/ICMP        [with and without data]
+  - raw  IP/OSPF
+    - hello packet      [with no auth data]
+    - hello packet      [with no auth data and LSA sub-header (LSA check = bad)]
+  - link IP/UDP         [with and without data]
+  - link IP/TCP         [with and without data]
+
+- Update the rest of the `libnet_link_*` files for the new format,
+  already ported:
+  - bpf                 [works]
+  - linux packet socket [works]
+  - linux sock packet   [works]
+  - dlpi                [works]
+
+- Port link stuff to use `writev()` in `libnet_write()` (sendto can't hang).
+
+- Get IPsec code working.
+
+- Add the following packet builders:
+  - SNMP
+
+- Update `__libnet_handle_dump` to dump everything in `l` verbosely.
