# NAME

File::Find::Upwards - Look for a file in the current directory and upwards

# SYNOPSIS

    use File::Find::Upwards qw(file_find_upwards);

    my $filename = file_find_upwards('myconfig.yaml');
    if ($filename) { rand() }

# DESCRIPTION

Provides functions that can find a file in the current or a parent directory.

- `file_find_upwards()`

Takes a filename and looks for the file in the current directory. If there is
no such file, it traverses up the directory hierarchy until it finds the file
or until it reaches the topmost directory. If the file is found, the full path
to the file is returned. If the file is not found, undef is returned.

The result is memoized, so repeated calls to the function with the same
filename will return the result of the first call for that filename.

This function is exported automatically.

- `find_containing_dir_upwards()`

Like `file_find_upwards()`, but reports the directory that contains the file.
A `Path::Class::Dir` object is returned.

This function is exported automatically.
