* === added directory bin, bin/ssh-auth-id, bin/ssh-auth-id-gh,
  bin/ssh-auth-id-lp, LICENSE, README.md, setup.py:
  - import Casey's subcommands implementation from his ssh-auth-id fork
    on github
* bin/ssh-auth-id => bin/ssh-import-id, bin/ssh-auth-id-gh => bin/ssh-
  import-id-gh, bin/ssh-auth-id-lp => bin/ssh-import-id-lp, README.md,
  setup.py:
  - rename Casey's ssh-auth-id command to ssh-import-id with this merge
* bin/ssh-import-id, bin/ssh-import-id-gh, bin/ssh-import-id-lp,
  setup.py:
  - get these pep8 clean with
     pep8 --verbose --repeat --ignore W191,E501
* bin/ssh-import-id:
  - drop the "starts with ssh-" check
  - bad assumption, since my ecdsa key starts with "ecdsa-sha2-nistp256"
  - if it's a bad key, then ssh-keygen -l -f will shake that out
* bin/ssh-import-id-lp:
  - support wget as a fallback, when python requests module is not available
loop over each id in argv
bin/ssh-import-id, bin/ssh-import-id-gh, bin/ssh-import-id-lp:
import subprocess
* setup.py:
  - bump major version to 3.x since this is a complete rewrite in Python
* === added directory attic, debian/control, ssh-import-id =>
  attic/ssh-import-id, ssh-import-id.py => attic/ssh-import-id.py:
  - relocate the old shell utility and the monolithic python utility to
    the attic for now; these should be removed entirely from the source
    tree in due time
* debian/install:
  - remove binaries from the install, let setup.py handle these for us
* bin/ssh-import-id:
  - support -o|--output - for stdout
  - return all parts of the fingerprint on validation (size, hash, name, type)
  - index into the fingerprint for the hash
  - print all parts of the fingerprint in info messages
    + this is essential to the security of ssh-import-id, for key fingerprint
      collision avoidance
use a helper function to print to stdout just as easily a filename
identify keys by their tuple, [length, hash, type]
* debian/links, README.md, ssh-import-id.1:
  - update documentation
add support for gh:username (github) as well as lp:username (launchpad)
* bin/ssh-import-id-lp, debian/postinst, ssh_import_id:
  - support URL environment variable and system-wide URL definition in conf
    file
  - port conf file from shell to JSON syntax
  - add a postinst script to smooth migration from ssh-import-id < 3.0
ignore errors in postinst script (nothing more we can do, really)
* bin/ssh-import-id-gh, bin/ssh-import-id-lp, debian/postinst,
  ssh_import_id:
  - use wget --no-verbose rather than --quiet, so that error messages from
    wget (such as SSL cert errors) get propagated
  - use json syntax for configuration file
