hgwebdir.cgi

Simplify/correct finding the hg executable (fixes issue644)

Simply use find_exe('hg') as the default value for $HG and require to manually
set it if you have special requirements.

While the default will not always be 100% correct (i.e. the identical hg
version) for many users it is and for the others the hg executable found in
the PATH should do most things correctly.

Developers or other users with multiple installs can set $HG or run something
like util.set_hgexecutable in their shell or python scripts.

Additionally util.hgexecutable() is now available so extensions can access
the value with a public interface, too.

#!/usr/bin/env python
#
# An example CGI script to export multiple hgweb repos, edit as necessary

# send python tracebacks to the browser if an error occurs:
import cgitb
cgitb.enable()

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

# If you'd like to serve pages with UTF-8 instead of your default
# locale charset, you can do so by uncommenting the following lines.
# Note that this will cause your .hgrc files to be interpreted in
# UTF-8 and all your repo files to be displayed using UTF-8.
#
#import os
#os.environ["HGENCODING"] = "UTF-8"

# The config file looks like this.  You can have paths to individual
# repos, collections of repos in a directory tree, or both.
#
# [paths]
# virtual/path = /real/path
# virtual/path = /real/path
#
# [collections]
# /prefix/to/strip/off = /root/of/tree/full/of/repos
#
# collections example: say directory tree /foo contains repos /foo/bar,
# /foo/quux/baz.  Give this config section:
#   [collections]
#   /foo = /foo
# Then repos will list as bar and quux/baz.
#
# Alternatively you can pass a list of ('virtual/path', '/real/path') tuples
# or use a dictionary with entries like 'virtual/path': '/real/path'
