Usage: %s [FLAGS]... [ARGUMENT]...
The wrapper $program shall search all nix
packages for a file and set up a nix shell for the
program that contains that file. The shell prints
all binaries in the package upon invocation.
Create and update the file database by running
the nix-index command. Warning: This command uses
up a large amount of memory.
nix-index --nixpkgs https://github.com/NixOS/nixpkgs/archive/master.tar.gz
Command List:
$program [ARGUMENT]... Search for packages using file name argument.
$program --help Show this help menu.
$program --check Check dependencies.
