TODO list for agedu
===================
-Before it's non-embarrassingly releasable:
+ - we should munmap in all operating modes where we mmapped,
+ otherwise chaining them will run out of address space
- - cross-Unix portability:
- + use autoconf
- * configure use of stat64
- * configure use of /proc/net/tcp
- * configure use of /dev/random
- * configure use of Linux syscall magic replacing readdir
- + later glibcs have fdopendir, hooray! So we can use that
- too, if it's available and O_NOATIME is too.
- * what do we do elsewhere about _GNU_SOURCE?
+ - we could still be using more of the information coming from
+ autoconf. Our config.h is defining a whole bunch of HAVE_FOOs for
+ particular functions (e.g. HAVE_INET_NTOA, HAVE_MEMCHR,
+ HAVE_FNMATCH). We could usefully supply alternatives for some of
+ these functions (e.g. cannibalise the PuTTY wildcard matcher for
+ use in the absence of fnmatch, switch to vanilla truncate() in
+ the absence of ftruncate); where we don't have alternative code,
+ it would perhaps be polite to throw an error at configure time
+ rather than allowing the subsequent build to fail.
+ + however, I don't see anything here that looks very
+ controversial; IIRC it's all in POSIX, for one thing. So more
+ likely this should simply wait until somebody complains.
- - man page, --version.

-Future possibilities:
+ - it would be useful to support a choice of indexing strategies.
+ The current system's tradeoff of taking O(N log N) space in order
+ to be able to support any age cutoff you like is not going to be
+ ideal for everybody. A second more conventional mechanism which
+ allows the user to specify a number of fixed cutoffs and just
+ indexes each directory on those alone would undoubtedly be a
+ useful thing for large-scale users. This will require
+ considerable thought about how to make the indexers pluggable at
+ both index-generation time and query time.
- IPv6 support in the HTTP server
* of course, Linux magic auth can still work in this context; we
