+//! Git style prompting with support for `GIT_ASKPASS` and `askpass` program configuration.
+//!
+//! ### Compatibility
+//!
+//! This is a unix-only crate which will return with an error when trying to obtain any prompt on other platforms.
+//! On those platforms it is common to have helpers which perform this task so it shouldn't be a problem.
