DESCRIPTION="A collection of file system and media management forensic analysis tools"
HOMEPAGE="https://www.sleuthkit.org/sleuthkit/"
# TODO: sqlite-jdbc does not exist in the tree, we bundle it for now
# TODO: Upstream uses a very specific version of libewf which is not in
#       the tree anymore. So we statically compile and link to sleuthkit.
#       Hopefully upstream will figure something out in the future.
