Synopsis: dircat [options] <directory>
This tool concatenates all files in a directory, writing the contents to
standard output. The contents of each file is preceded with a line
containing the path of the file.
The current features are very simple. The directory must contain only
regular files. It is an error if the directory contains subdirectories
or symbolic links.
Exit status is '0' on success, '1' if an error occurred.
