Seems like the re module is not being used here.

Nit: for setting in settings.itervalues() - the key isn't being used.

+    tempdir = mkdtemp(prefix='external')
+    try:
+      repoPath = setting['targetrepository']
+      targetPath = os.path.dirname(setting['targetfile'])
+      filename = os.path.basename(setting['targetfile'])
+      
+      subprocess.Popen(['hg', 'clone', '-q', '-U', repoPath, tempdir], stdout=subprocess.PIPE).communicate()
+      subprocess.Popen(['hg', 'up', '-q', '-R', tempdir, '-r', 'default'], stdout=subprocess.PIPE).communicate()
+      
+      path = os.path.join(tempdir, targetPath)
+      if not os.path.exists(path):
+        os.makedirs(path)
+      
+      path = os.path.join(path, filename)
+      exists = os.path.exists(path)
+      file = codecs.open(path, 'wb', encoding='utf-8')
+      data = urllib.urlopen(setting['source']).read()

You need to add .decode('utf-8') at the end - as is this is being interpreted as
ASCII data and will cause issues if the file has non-ASCII content.

+      file.write(data)
+      file.close()
+
+      message = 'Updated copy of external file %s'
+      if not exists:
+        message = 'Added copy of external file %s'
+      subprocess.Popen(['hg', 'commit', '-q', '-A', '-R', tempdir, '-u', 'hgbot', '-m', message % filename], stdout=subprocess.PIPE).communicate()
+      subprocess.Popen(['hg', 'push', '-q', '-R', tempdir], stdout=subprocess.PIPE).communicate()
+    finally:
+      rmtree(tempdir)
+
+def readSettings():
+  result = {}
+  for option, value in get_config().items('externalFiles'):
+    if option.find('_') < 0:
+      continue
+    name, setting = option.rsplit('_', 2)
+    if not setting in ('source', 'targetrepository', 'targetfile'):
+      continue
+
+    if not name in result:
+      result[name] = {
+        'source': None,
+        'targetrepository': None,
+        'targetfile': None
+      }
+    result[name][setting] = value
+  return result
