current version 0.2.7 (Feb. 4, 2009)  Compiles nicely now on gcc 4.3.x

version 0.2.6 (May 15, 2008) Fixed bug in description of frequency filter option (-m) that affected several programs.  Also, tohudson2001 now outputs characters instead of integers on systems using current versions of gcc.  This was a bug due to not typecasting the return value of toupper to char.

version 0.2.5 (Jan 22, 2008) Use of "getopt" now behaves properly on Apple's "Leopard".

version 0.2.4 (Sept. 21, 2005)  output from tohudson2001 is now all
uppercase, which makes sure that it is compatible with Hudson's program

version 0.2.3 (Jan 12, 2003) -- configure script now checks for
required headers.

version 0.2.2 (Nov 1, 2003) -- compatible (and requires) libsequence
>= 1.3.3

version 0.2.1 (Jul 29th 2003) -- mstoexhap now works with latest version of exhap

version 0.2.0 -- compatible with gcc 2.95.  output of tohudson2001
and mstoexhap now slightly different (compatible with latest versions of
Hudson's rho estimation programs).

version 0.1.8 -- updated to libsequence 1.2.1

version 0.1.7 -- compatible with libsequence >= 1.1.7

version 0.1.6 -- tohudson2001 and toLDhat now use a common code
base, and both work to combine multiple FASTA files into 1 output.  There
are still some limitations in interface and functionality, but they are
working well for the moment

version 0.1.5 -- tohudson2001 now works with multiple files.  No
outgroup support yet, and individuals must be in the same order in all files.

version 0.1.4 -- now work with g++3 on OS X

version 0.1.3: mstoexhap now takes a -d flag.  If you use this flag,
samples are assumed to be "a/d specified", i.e. 0 is ancestral, 1 is
derived.  If the flag is not used, ancestral,derived are assumed to be unknown

version: 0.1.2 -- mstoexhap now assums a-d unspecified samples (i.e.
the outgroup is assumed to be unknown).  The previous version output a 0
(indicating ancestral) for the outgroup state, which was incorrect.

version: 0.1.1 -- update to libsequence 1.0.4, resulting in
mstoexhap being much faster
