f61d14aabf a WebP encoder
converts PNG & JPEG to WebP

This is an experimental early version, with lot of room
of later optimizations in both speed and quality.

Compile with the usual `./configure && make`
Command line example is examples/cwebp

Usage:

   cwebp [options] -q quality input.png -o output.webp

where 'quality' is between 0 (poor) to 100 (very good).
Typical value is around 80.

More encoding options with 'cwebp -longhelp'

83b545eea7 add vc9+ makefile
nmake /F Makefile.vc9 cfg=release-static
    objdir=h:\projects\webp\repo\build\libwebp ARCH=x64

given that you are in x64 mode, this command will build libwebp in
the <objdir>\release-static
