git mv *.hint -> README.md

There is one exception:

    $ find . -name '*.hint' -execdir git mv '{}' README.md \;
    git statufatal: destination exists, source=1992/albert/albert.hint, destination=1992/albert/README.md

Looking at the two files they differ quite a bit so I've not changed it.
I'll bring this up on GitHub.

+    To build:
+
+	make tomtorfs
+
+    To use:
+
+	./tomtorfs tomtorfs.c 32 04C11DB7 1 FFFFFFFF FFFFFFFF
+
+    Also try:
+
+	echo "abscond conferrable" > file.A
+	echo "adorn condolence" > file.B
+	echo "adorn condolence too" > file.C
+	./tomtorfs file.A 32 04C11DB7 1 FFFFFFFF FFFFFFFF
+	./tomtorfs file.B 32 04C11DB7 1 FFFFFFFF FFFFFFFF
+	./tomtorfs file.C 32 04C11DB7 1 FFFFFFFF FFFFFFFF
+
+    If you don't believe the program is correct, try and compare the output
+    of the program with the value of CRC computed by PKZIP or any other
+    archiver that uses the CRC-32 algorithm.

+    Usage:
+       crc filename bitwidth polynom reflected init xor
+
+       filename  : file to calculate the CRC of
+       bitwidth  : width of the CRC in bits (decimal)
+       polynom   : polynomial used for the CRC (hexadecimal)
+       reflected : 0 if the CRC is not reflected, 1 if it is
+       init      : initial value for the CRC (hexadecimal)
+       xor       : value to xor the final CRC with (hexadecimal)
+
+    Examples:
+
+       CRC-16: crc filename 16 1021 0 FFFF 0000
+       CRC-32: crc filename 32 04C11DB7 1 FFFFFFFF FFFFFFFF
+       XMODEM: crc filename 16 8408 1 0000 0000
+       ARC:    crc filename 16 8005 1 0000 0000
+
+    Portability notes:
+
+       The program assumes CHAR_BIT==8. Results are undefined if
+       bitwidth > sizeof(unsigned long) * 8. It is also assumed
+       that EOF is -1 and 1 is a valid exit value to indicate
+       failure (replace them with EOF resp. EXIT_FAILURE if the
+       assumptions are false). Otherwise ANSI/ISO C.
+       No special build options required.
+
+    Special notes:
+
+       Count the number of non-whitespace characters in the source
+       file to find out what dark force drove me to write this ;-).
+
+    Spoiler:
+
+       First of all, if you run a C beautifier on the program
+       (thereby of course losing the nice code shape I worked
+        so hard on ;-) the code will become a bit more readable.
+
+       The variable names are not very descriptive. They have the
+       following meanings:
+          a = argc
+          A = argv
+          b = array of unsigned long variables
+              b[0] = bit-width of the CRC (argv[2])
+              b[1] = CRC polynomial (argv[3])
+              b[2] = nonzero if CRC is reflected (argv[4])
+              b[3] = initial value of CRC (argv[5])
+              b[4] = value final CRC is XORed with (argv[6])
+              b[5] = CRC value
+              b[6] = byte from file
+              b[7] = counter
+          B = FILE * through which the file argv[1] is opened
+          C = typedef for unsigned long
+
+       The first for loop simply reads the command-line arguments
+       in the b[] array. The third parameter to strtoul() causes
+       all arguments to be in base-16 (hex) except the first one,
+       which will be in base-10 (decimal).
+
+       The rest of the program "simply" calculates the crc in b[5]
+       and then prints it to stdout. The bit reflection loops may
+       appear a bit tricky at first, but if you have a good look
+       at them they should become obvious also.

+       for writing this. You can find it as CRC.TXT in Snippets.
