This program is an improvement over the standard Linux help utility.
Instead of just printing out a static list of built-in commands with no descriptions, betterhelp runs on all files in /bin by default and uses data from man files.
-n/--nocache: Disables caching. This option can also be controlled with a #define.-r/--rebuildcache: Rebuilds the description (.bhmans) cache-v/--verbose: Adds extra logging- Positional argument (without a flag): Display help for the given command by running it with the --help flag
