# NOTE We disable this for now, because:
#
# # Putting tiny, crappy, rust newb-projects on crates.io?
# or
# # How to publish  tiny, crappy, rust newb-projects?
#
# ... to not pollute the global name-space.
#
# ## Solutions
#
# ### Name
#
# You can just name them "hoijui-shitty-project1" or something.
#
# ### Not on crates.io
#
# ... but personally,
# I wouldn't upload them to crates.io unless I was sure it's something that:
#
# a) I want to commit maintaining
# b) is something other people will find useful.
#
# You can still have your project on your github and have people use it easily, see:
# <https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#specifying-dependencies-from-git-repositories>
#
# This also works wih `cargo install`, if it is some command line tool.
#
# The only real restriction is,
# that if other people depend on your github repo,
# they wouldn't then be able to publish their own stuff on crates.io,
# because github dependencies aren't allowed there.
# So you'd probably want to use a license that permits them to fork/copy your code.
