 Crates to package
 =================
 
+
+Eventual goals
+==============
+
+To see lists of interesting binary crates, you can run something like::
+
+  $ apt-get install koji-client
+  $ koji -p fedora search package 'rust-*' | cut -b6- | dev/filter-binary-crates.sh
+
+Current output (on 2018-07-08) is:
+
+- aho-corasick
+- docopt
+- pulldown-cmark
+- ripgrep
+- fd-find
+- exa
+- cpp_demangle
+- permutate
+- cbindgen
+- rustdoc-stripper
+- difference
+- pretty-git-prompt
+- peg
+- varlink
+- varlink-cli
