+# Docs:
+#
+# If you source this file from your .bashrc, bash should be able to
+# complete a command line that uses hg with all the available commands
+# and options and sometimes even arguments.
+#
+# Mercurial allows you to define additional commands through extensions.
+# Bash should be able to automatically figure out the name of these new
+# commands and their options.  If you also want to tell it how to
+# complete non-option arguments, see below for how to define an
+# _hg_cmd_foo function.
+#
+#
+# Notes about completion for specific commands:
+#
+# - the completion function for the email command from the patchbomb
+#   extension will try to call _hg_emails to get a list of e-mail
+#   addresses.  It's up to the user to define this function.  For
+#   example, put the addresses of the lists that you usually patchbomb
+#   in ~/.patchbomb-to and the addresses that you usually use to send
+#   the patchbombs in ~/.patchbomb-from and use something like this:
+#
+#      _hg_emails()
+#      {
+#          if [ -r ~/.patchbomb-$1 ]; then
+#              cat ~/.patchbomb-$1
+#          fi
+#      }
+# 
+#
+# Writing completion functions for additional commands:
+#
+# If it exists, the function _hg_cmd_foo will be called without
+# arguments to generate the completion candidates for the hg command
+# "foo".
+#
+# In addition to the regular completion variables provided by bash,
+# the following variables are also set:
+# - $hg - the hg program being used (e.g. /usr/bin/hg)
+# - $cmd - the name of the hg command being completed
+# - $cmd_index - the index of $cmd in $COMP_WORDS
+# - $cur - the current argument being completed
+# - $prev - the argument before $cur
+# - $global_args - "|"-separated list of global options that accept
+#                  an argument (e.g. '--cwd|-R|--repository')
+# - $canonical - 1 if we canonicalized $cmd before calling the function
+#                0 otherwise
+#
