+This is the popt(3) command line option parsing library. While it is similiar
+to getopt(3), it contains a number of enhancements, including:
+
+ 1) popt is fully reentrant
+ 2) popt can parse arbitrary argv[] style arrays while
+ getopt(3) makes this quite difficult
+ 3) popt allows users to alias command line arguments
+ 4) popt provides convience functions for parsing strings
+ into argv[] style arrays
+
+Complete documentation on popt(3) is available in popt.ps (included in this
+tarball), which is excerpted with permission from the book "Linux
+Application Development" by Michael K. Johnson and Erik Troan (available
+from Addison Wesley in May, 1998).
+
+Comments on popt should be addressed to popt-devel@rpm5.org.

+ * lookup3.c, by Bob Jenkins, May 2006, Public Domain.
+ *
+ * These are functions for producing 32-bit hashes for hash table lookup.
+ * jlu32w(), jlu32l(), jlu32lpair(), jlu32b(), _JLU3_MIX(), and _JLU3_FINAL()
+ * are externally useful functions. Routines to test the hash are included
+ * if SELF_TEST is defined. You can use this free for any purpose. It's in
+ * the public domain. It has no warranty.
+ *
+ * You probably want to use jlu32l(). jlu32l() and jlu32b()
+ * hash byte arrays. jlu32l() is is faster than jlu32b() on
+ * little-endian machines. Intel and AMD are little-endian machines.
+ * On second thought, you probably want jlu32lpair(), which is identical to
+ * jlu32l() except it returns two 32-bit hashes for the price of one.
+ * You could implement jlu32bpair() if you wanted but I haven't bothered here.
+ *
+ * If you want to find a hash of, say, exactly 7 integers, do
+ * a = i1; b = i2; c = i3;
+ * _JLU3_MIX(a,b,c);
+ * a += i4; b += i5; c += i6;
+ * _JLU3_MIX(a,b,c);
+ * a += i7;
+ * _JLU3_FINAL(a,b,c);
+ * then use c as the hash value. If you have a variable size array of
+ * 4-byte integers to hash, use jlu32w(). If you have a byte array (like
+ * a character string), use jlu32l(). If you have several byte arrays, or
+ * a mix of things, see the comments above jlu32l().
+ *
+ * Why is this so big? I read 12 bytes at a time into 3 4-byte integers,
+ * then mix those integers. This is fast (you can do a lot more thorough
+ * mixing with 12*3 instructions on 3 integers than you can with 3 instructions
+ * on 1 byte), but shoehorning those bytes into integers efficiently is messy.

+ *
+ * This is reversible, so any information in (a,b,c) before _JLU3_MIX() is
+ * still in (a,b,c) after _JLU3_MIX().
+ *
+ * If four pairs of (a,b,c) inputs are run through _JLU3_MIX(), or through
+ * _JLU3_MIX() in reverse, there are at least 32 bits of the output that
+ * are sometimes the same for one pair and different for another pair.
+ * This was tested for:
+ * * pairs that differed by one bit, by two bits, in any combination
+ * of top bits of (a,b,c), or in any combination of bottom bits of
+ * (a,b,c).
+ * * "differ" is defined as +, -, ^, or ~^. For + and -, I transformed
+ * the output delta to a Gray code (a^(a>>1)) so a string of 1's (as
+ * is commonly produced by subtraction) look like a single 1-bit
+ * difference.
+ * * the base values were pseudorandom, all zero but one bit set, or
+ * all zero plus a counter that starts at zero.
+ *
+ * Some k values for my "a-=c; a^=ROTL32(c,k); c+=b;" arrangement that
+ * satisfy this are
+ * 4 6 8 16 19 4
+ * 9 15 3 18 27 15
+ * 14 9 3 7 17 3
+ * Well, "9 15 3 18 27 15" didn't quite get 32 bits diffing
+ * for "differ" defined as + with a one-bit base and a two-bit delta. I
+ * used http://burtleburtle.net/bob/hash/avalanche.html to choose
+ * the operations, constants, and arrangements of the variables.
+ *
+ * This does not achieve avalanche. There are input bits of (a,b,c)
+ * that fail to affect some output bits of (a,b,c), especially of a. The
+ * most thoroughly mixed value is c, but it doesn't really even achieve
+ * avalanche in c.
+ *
+ * This allows some parallelism. Read-after-writes are good at doubling
+ * the number of bits affected, so the goal of mixing pulls in the opposite
+ * direction as the goal of parallelism. I did what I could. Rotates
+ * seem to cost as much as shifts on every machine I could lay my hands
+ * on, and rotates are much kinder to the top and bottom bits, so I used
+ * rotates.
