//! # Library doc
//!
//! This library is used by `cargo-update` itself for all its function and is therefore contains all necessary functions.
//!
//! ## Example
//!
//! See the [`src/main.rs`](https://github.com/nabijaczleweli/cargo-update/blob/master/src/main.rs) file in the git repository.

//!
//! ## SYNOPSIS
//!
//! [`cargo install-update`](https://github.com/nabijaczleweli/cargo-update) [OPTIONS] [PACKAGE...]
//!
//! ## DESCRIPTION
//!
//!
//! Cargo subcommand for checking and applying updates to installed executables.
//!
//! This was mostly built out of a frustration with periodically checking for
//! updates for my cargo-installed executables, which was long and boring.
//!
//! Updates packages from the main repository and git repositories.
//!
//! See
//! [cargo-install-update-config(1)](https://rawcdn.githack.com/nabijaczleweli/cargo-update/man/cargo-install-update-config.1.html)
//! for further configuring updates.
//!
//! The `CARGO_INSTALL_OPTS` environment variable can be set,
//! containing options to forward to the end of `cargo install` invocations'
//! argument lists.
//! Note, that
//! [cargo-install-update-config(1)](https://rawcdn.githack.com/nabijaczleweli/cargo-update/man/cargo-install-update-config.1.html)
//! is preferred in the general case.
//!
//! Exit values and possible errors:
//!
//! ```text
//! -1 - cargo subprocess was terminated by a signal (Linux-only)
//! 1  - option parsing error
//! 2  - registry repository error
//! X  - bubbled-up cargo install exit value
//! ```
//!
//! ## OPTIONS
//!
//! -a --all
//!
//! ```text
//! Update all currently installed executables.
//!
//! Required if list of packages not given.
//! ```
//!
//! [PACKAGE...]
//!
//! ```text
//! List of packages to update in the [(registry_url):]package_name[:version] format.
//!
//! Registry defaults to the default crates.io registry,
//! and can be a name from ~/.cargo/config.
//!
//! If specified in addition to --all,
//! will add the specified packages to the update list
//! (useful, e.g., in conjunction with --allow-no-update).
//!
//! Required if --all not given.
//! ```
//!
//! -l --list
//!
//! ```text
//! Don't update any packages, just list them.
//!
//! If PACKAGE is empty, act as if --all was specified.
//! ```
//!
//! -f --force
//!
//! ```text
//! Update all packages, regardless of whether they need to be version-wise.
//! ```
//!
//! -i --allow-no-update
//!
//! ```text
//! Allow to fresh install packages passed as PACKAGE argument.
//!
//! This is useful, for example, in pairing with cargo-install-update-config(1).
//!
//! Off by default.
//! ```
//!
//! -g --git
//!
//! ```text
//! Also update git-originating packages.
//!
//! Off by default, because it's expensive.
//! ```
//!
//! -q --quiet
//!
//! ```text
//! Don't print status messages to stdout
//! and pass down --quiet to cargo subprocesses.
//! ```
//!
//! -s --filter <PACKAGE_FILTER>...
//!
//! ```text
//! Only consider packages matching all filters.
//!
//! PACKAGE_FILTER is in the form "key=value", where key is any of:
//!   - "toolchain": the package must be configured to be compiled with
//!                  the specified toolchain via cargo-install-update-config(1).
//! ```
//!
//! -c --cargo-dir <CARGO_DIR>
//!
//! ```text
//! Set the directory containing cargo metadata.
//!
//! Required. Default: "$CARGO_HOME", then "$HOME/.cargo", otherwise manual.
//! ```
//!
//! -t --temp-dir <TEMP_DIR>
//!
//! ```text
//! Set the directory in which to clone git repositories.
//!
//! Adjoined with "cargo-update" as last segment.
//!
//! Required. Default: system temp, otherwise manual.
//! ```
//!
//! ## EXAMPLES
//!
//! `cargo install-update -a`
//!
//! ```text
//! Update all installed packages.
