This package resides here because the ebuild file deviates from the upstream version. This is done so we can configure the correct data directory for vim on ChromeOS dev and test images. The default data directory for vim and vim-core is /usr/share/... whereas the installation directory for dev and test images is /use/local/share/.... This causes issues as vim is not able to locate the artifact files on dev and test images.

When upreving vim and vim-core please remember to add the following line in the src_configure() function, and append cros_host to the list of IUSE flags at the top of the ebuild. ! use cros_host && myconf+=( --datadir=/usr/local/share )
