+//! A crate for using libcurl as a backend for HTTP git requests with git2-rs.
+//!
+//! This crate provides one public function, `register`, which will register
+//! a custom HTTP transport with libcurl for any HTTP requests made by libgit2.
+//! At this time the `register` function is unsafe for the same reasons that
+//! `git2::transport::register` is also unsafe.
+//!
+//! It is not recommended to use this crate wherever possible. The current
+//! libcurl backend used, `curl-rust`, only supports executing a request in one
+//! method call implying no streaming support. This consequently means that
+//! when a repository is cloned the entire contents of the repo are downloaded
+//! into memory, and *then* written off to disk by libgit2 afterwards. It
+//! should be possible to alleviate this problem in the future.
+//!
+//! > **NOTE**: At this time this crate likely does not support a `git push`
+//! > operation, only clones.
