hgwebdir.cgi

make mercurial look in more places for config files.

now it searches <install dir>/etc/mercurial, /etc/mercurial, and user
hgrc.

this allows site-wide configuration to be shared over automounted nfs
partition, instead of chenging on every system.  option of having local
configuration on every system remains.

old code for searching /etc/mercurial/hgrc.d never worked, this code
is tested and works.

#!/usr/bin/env python

# An example CGI script to export multiple hgweb repos, edit as necessary

import cgitb, sys
cgitb.enable()

# sys.path.insert(0, "/path/to/python/lib") # if not a system-wide install
from mercurial import hgweb

# The config file looks like this:
# [paths]
# virtual/path = /real/path
# virtual/path = /real/path

# Alternatively you can pass a list of ('virtual/path', '/real/path') tuples
# or use a dictionary with entries like 'virtual/path': '/real/path'

h = hgweb.hgwebdir("hgweb.config")
h.run()
