There was a problem hiding this comment.
Nitpick but this would be generally easier to understand using the positive form:
if File.exists?(path)
do B
else
do A
end
Instead of if !x do A else do B

Since we store the optimization manifest in the
builddirectory, and since it doesn't have a counterpart in thesourcedirectory theManifestResourceneeds to behave a little differently than your average resource. Instead of reading a file fromsourceand writing it tobuildwe want to read frombuildif the file already exists, so that we preserve the contents of that file through the first stage of the build.In one of my projects this PR takes a 22 minute build down to 2 minutes.
Fixes #60
Fixes #41, Closes #58 (Specifying the manifest path shouldn't be needed if we don't overwrite it, and storing it outside the build directory doesn't exactly make sense since it is an artifact of a particular build, or sequence of builds. To say it another way, if you used an existing manifest with an empty build directory you'd end up skipping optimization of images that would need to be optimized.)
