usage: harvest.py [-h] [-d | -s] [-v] [-e EXTENSION] [-p] source [source ...]

Harvests files in one or more directory trees and writes all the content to
stdout.

positional arguments:
  source                path to harvest content

optional arguments:
  -h, --help            show this help message and exit
  -d, --depth-first     sorts the files so the deeper paths comes before the
                        shallow ones, and directories comes before the files
                        (following the pattern used by most file managers and
                        IDEs)
  -s, --shallow-first   sorts the files so the shallow paths comes before the
                        deep ones (the opposite of --depth-first
  -v, --verbose         display errors (errors are written to stderr)
  -e EXTENSION, --extension EXTENSION
                        set a file extension to consider
  -p, --paths-only      write only the file paths to stdout

Multiple extensions can be provided by repeating the '-e' extension argument
(eg. '-e .txt -e .readme'). By default the files are sorted using alphabetial
order. To sort them by depth use --depth-first or --shallow-first arguments.
