1 Plan: do away with shell scripts, and un-hard-wire the path /usr/local/lib/mercurial-server.

     3 Steps:

     4 

     5 - move all modules into mercurial_server directory

     6 - make mercurial_server.paths module; a function sets a global based on sys.argv[0]

     7 - reduce hg-ssh-wrapper to nothing by moving all functionality into hg-ssh

     8 - same for refresh-auth

     9 - move most of do-refresh-auth into a module

    10 - give that module a hook, and call the hook instead of the exe

    11 - abolish refresh-auth shell script and rename do-refresh-auth to refresh-auth

    12 - replace env vars with Python globals

    13 - change refresh-auth to refer to hg-ssh directly, abolish hg-ssh-wrapper

    14 - add comment check and -f flag to refresh-auth

    15 - change install script to a Python script, abolishing hginit
