A cargo subcommand to check that all target files have a fixed prefix. This may be useful for licence headers, ensuring particular clippy lints are en/disabled, or maybe some other things too.
``` cargo-ensure-prefix
USAGE:
cargo-ensure-prefix [FLAGS] [OPTIONS] --manifest-path
FLAGS:
--all
-h, --help Prints help information
-V, --version Prints version information
OPTIONS:
--manifest-path
-p, --package
--prefix-path
Any byte will be accepted where a character \x1A is present in the prefix file. e.g. you could match any set of 4-digit years with a prefix file with contents: Copyright \x1A\x1A\x1A\x1A. Note that this is byte-wise matching, not character-wise matching.
