-//!
-//! fn main() {
-//! debug!("this is a debug {:?}", "message");

-//!
-//! if log_enabled!(log::INFO) {
-//! let x = 3 * 4; // expensive computation
-//! info!("the answer was: {:?}", x);
-//! }
-//! }
-//! ```
-//!
-//! Assumes the binary is `main`:
-//!
-//! ```{.bash}
-//! $ RUST_LOG=error ./main
-//! ERROR:main: this is printed by default
-//! ```
-//!
-//! ```{.bash}
-//! $ RUST_LOG=info ./main
-//! ERROR:main: this is printed by default
-//! INFO:main: the answer was: 12

-//! DEBUG:main: this is a debug message

-//! $ RUST_LOG=main=info ./main
-//! ERROR:main: this is printed by default
-//! INFO:main: the answer was: 12
-//! ```
-//!
-//! And enable all logging:

-//! DEBUG:main: this is a debug message
-//! ERROR:main: this is printed by default
-//! INFO:main: the answer was: 12
-//! ```
-//!
-//! # Logging Macros
-//!
-//! There are five macros that the logging subsystem uses:
-//!
-//! * `log!(level, ...)` - the generic logging macro, takes a level as a u32 and any
-//! related `format!` arguments
-//! * `debug!(...)` - a macro hard-wired to the log level of `DEBUG`
-//! * `info!(...)` - a macro hard-wired to the log level of `INFO`
-//! * `warn!(...)` - a macro hard-wired to the log level of `WARN`
-//! * `error!(...)` - a macro hard-wired to the log level of `ERROR`
-//!
-//! All of these macros use the same style of syntax as the `format!` syntax
-//! extension. Details about the syntax can be found in the documentation of
-//! `std::fmt` along with the Rust tutorial/manual.
-//!
-//! If you want to check at runtime if a given logging level is enabled (e.g. if the
-//! information you would want to log is expensive to produce), you can use the
-//! following macro:
-//!
-//! * `log_enabled!(level)` - returns true if logging of the given level is enabled
-//!
-//! # Enabling logging
-//!
-//! Log levels are controlled on a per-module basis, and by default all logging is
-//! disabled except for `error!` (a log level of 1). Logging is controlled via the
-//! `RUST_LOG` environment variable. The value of this environment variable is a
-//! comma-separated list of logging directives. A logging directive is of the form:
-//!
-//! ```text
-//! path::to::module=log_level
-//! ```
-//!
-//! The path to the module is rooted in the name of the crate it was compiled for,
-//! so if your program is contained in a file `hello.rs`, for example, to turn on
-//! logging for this file you would use a value of `RUST_LOG=hello`.
-//! Furthermore, this path is a prefix-search, so all modules nested in the
-//! specified module will also have logging enabled.
-//!
-//! The actual `log_level` is optional to specify. If omitted, all logging will be
-//! enabled. If specified, the it must be either a numeric in the range of 1-255, or
-//! it must be one of the strings `debug`, `error`, `info`, or `warn`. If a numeric
-//! is specified, then all logging less than or equal to that numeral is enabled.
-//! For example, if logging level 3 is active, error, warn, and info logs will be
-//! printed, but debug will be omitted.
-//!
-//! As the log level for a module is optional, the module to enable logging for is
-//! also optional. If only a `log_level` is provided, then the global log level for
-//! all modules is set to this value.
-//!
-//! Some examples of valid values of `RUST_LOG` are:
-//!
-//! * `hello` turns on all logging for the 'hello' module
-//! * `info` turns on all info logging
-//! * `hello=debug` turns on debug logging for 'hello'
-//! * `hello=3` turns on info logging for 'hello'
-//! * `hello,std::option` turns on hello, and std's option logging
-//! * `error,hello=warn` turn on global error logging and also warn for hello
-//!
-//! # Filtering results
-//!
-//! A RUST_LOG directive may include a string filter. The syntax is to append
-//! `/` followed by a string. Each message is checked against the string and is
-//! only logged if it contains the string. Note that the matching is done after
-//! formatting the log string but before adding any logging meta-data. There is
-//! a single filter for all modules.
-//!
-//! Some examples:
-//!
-//! * `hello/foo` turns on all logging for the 'hello' module where the log message
-//! includes 'foo'.
-//! * `info/f.o` turns on all info logging where the log message includes 'foo',
-//! 'f1o', 'fao', etc.
-//! * `hello=debug/foo*foo` turns on debug logging for 'hello' where the log
-//! message includes 'foofoo' or 'fofoo' or 'fooooooofoo', etc.
-//! * `error,hello=warn/[0-9] scopes` turn on global error logging and also warn for
-//! hello. In both cases the log message must include a single digit number
-//! followed by 'scopes'
-//!
-//! # Performance and Side Effects
-//!
-//! Each of these macros will expand to code similar to:
-//!
-//! ```rust,ignore
-//! if log_level <= my_module_log_level() {
-//! ::log::log(log_level, format!(...));
-//! }
-//! ```
-//!
-//! What this means is that each of these macros are very cheap at runtime if
-//! they're turned off (just a load and an integer comparison). This also means that
-//! if logging is disabled, none of the components of the log will be executed.
