/// cargo-temp: Create temporary Rust projects with specified dependencies.

/// A Cargo subcommand for quick experimentation. It creates a temporary project, adds any
/// dependencies you specify and drops you into a shell.

        "Each dependency is:
- A NAME from crates.io
- A git URL (http/https/ssh)
- A local PATH (./, ../, /, or X:\\ prefix).

A git URL may include `#BRANCH`, `#TAG`, or `#REV` to select a ref. The ref is
treated as a branch unless it is 7+ hex digits (revision) or looks like a
version (tag). Use an explicit prefix (`#branch:`, `#tag:`, `#rev:`) to
override the detection.

Version: `<OP><VERSION>` where OP is:
- `=` or `==` (exact)
- `>` (greater)
- `<` (less)
- `>=` (greater or equal)
- `<=` (less or equal)
- `~` (major.minor compatible)

Features: `+<FEATURE>` (repeatable).
`+` alone disables defaults.
`++name` does both (disables defaults and adds the feature).
Version must precede features.

Examples:
    anyhow
    tokio=1.48
    clap+derive
    anyhow=1.0.100+backtrace
