# This module manages standard configuration file handling
# These classes are available:
# Conf:
#  This is the base class.  This is good for working with just about
#  any line-oriented configuration file.
#  Currently does not deal with newline escaping; may never...
# ConfShellVar(Conf):
#  This is a derived class which implements a dictionary for standard
#  VARIABLE=value
#  shell variable setting.
#  Limitations:
#    o one variable per line
#    o assumes everything on the line after the '=' is the value
# ConfShellVarClone(ConfShellVar):
#  Takes a ConfShellVar instance and records in another ConfShellVar
#  "difference file" only those settings which conflict with the
#  original instance.  The delete operator does delete the variable
#  text in the cloned instance file, but that will not really delete
#  the shell variable that occurs, because it does not put an "unset"
#  command in the file.
# ConfESNetwork(ConfShellVar):
#  This is a derived class specifically intended for /etc/sysconfig/network
#  It is another dictionary, but magically fixes /etc/HOSTNAME when the
#  Hostname is changed.
# ConfEHosts(Conf):
#  Yet another dictionary, this one for /etc/hosts
#  Dictionary keys are numeric IP addresses in string form, values are
#  2-item lists, the first item of which is the canonical Hostname,
#  and the second of which is a list of nicknames.
# ConfEResolv(Conf):
#  Yet another dictionary, this one for /etc/resolv.conf
#  This ugly file has two different kinds of entries.  All but one
#  take the form "key list of arguments", but one entry (nameserver)
#  instead takes multiple lines of "key argument" pairs.
#  In this dictionary, all keys have the same name as the keys in
#  the file, EXCEPT that the multiple nameserver entries are all
#  stored under 'nameservers'.  Each value (even singleton values)
#  is a list.
# ConfESStaticRoutes(Conf):
#  Yet another dictionary, this one for /etc/sysconfig/static-routes
#  This file has a syntax similar to that of /etc/gateways;
#  the interface name is added and active/passive is deleted:
#  <interface> net <netaddr> netmask <netmask> gw <gateway>
#  The key is the interface, the value is a list of
#  [<netaddr>, <netmask>, <gateway>] lists
# ConfChat(Conf):
#  Not a dictionary!
#  This reads chat files, and writes a subset of chat files that
#  has all items enclosed in '' and has one expect/send pair on
#  each line.
#  Uses a list of two-element tuples.
# ConfChatFile(ConfChat):
#  This class is a ConfChat which it interprets as a netcfg-written
#  chat file with a certain amount of structure.  It interprets it
#  relative to information in an "ifcfg-" file (devconf) and has a
#  set of abortstrings that can be turned on and off.
#  It exports the following data items:
#    abortstrings   list of standard strings on which to abort
#    abortlist      list of alternative strings on which to abort
#    defabort       boolean: use the default abort strings or not
#    dialcmd        string containing dial command (ATDT, for instance)
#    phonenum       string containing phone number
#    chatlist       list containing chat script after CONNECT
#    chatfile       ConfChat instance
# ConfChatFileClone(ConfChatFile):
#  Creates a chatfile, then removes it if it is identical to the chat
#  file it clones.
# ConfDIP:
#  This reads chat files, and writes a dip file based on that chat script.
#  Takes three arguments:
#   o The chatfile
#   o The name of the dipfile
#   o The ConfSHellVar instance from which to take variables in the dipfile
# ConfModules(Conf)
#  This reads /etc/modprobe.d/dist.conf into a dictionary keyed on device type,
#  holding dictionaries: cm['eth0']['alias'] --> 'smc-ultra'
#                        cm['eth0']['options'] --> {'io':'0x300', 'irq':'10'}
#                        cm['eth0']['post-install'] --> ['/bin/foo', 
#                                                        'arg1', 'arg2']
#  path[*] entries are ignored (but not removed)
#  New entries are added at the end to make sure that they
#  come after any path[*] entries.
#  Comments are delimited by initial '#'
# ConfModInfo(Conf)
#  This READ-ONLY class reads /boot/module-info.
#  The first line of /boot/module-info is "Version = <version>";
#  this class reads versions 0 and 1 module-info files.
# ConfPw(Conf)
#  This class implements a dictionary based on a :-separated file.
#  It takes as arguments the filename and the field number to key on;
#  The data provided is a list including all fields including the key.
#  Has its own write method to keep files sane.
# ConfPasswd(ConfPw)
#  This class presents a data-oriented class for making changes
#  to the /etc/passwd file.
# ConfShadow(ConfPw)
#  This class presents a data-oriented class for making changes
#  to the /etc/shadow file.
# ConfGroup(ConfPw)
#  This class presents a data-oriented class for making changes
#  to the /etc/group file.
#  May be replaced by a pwdb-based module, we hope.
# ConfUnix()
#  This class presents a data-oriented class which uses the ConfPasswd
#  and ConfShadow classes (if /etc/shadow exists) to hold data.
#  Designed to be replaced by a pwdb module eventually, we hope.
# ConfPAP(Conf):
#  Yet another dictionary, this one for /etc/ppp/pap-secrets
#  The key is the remotename, the value is a list of
#  [<user>, <secret>] lists
# ConfCHAP(ConfPAP):
#  Yet another dictionary, this one for /etc/ppp/chap-secrets
#  The key is the remotename, the value is a list of
#  [<local>, <secret>] lists
# ConfSecrets:
#  Has-a ConfPAP and ConfCHAP
#  Yet another dictionary, which reads from pap-secrets and
#  chap-secrets, and writes to both when an entry is set.
#  When conflicts occur while reading, the pap version is
#  used in preference to the chap version (this is arbitrary).
# ConfSysctl:
#  Guess what?  A dictionary, this time with key/value pairs for sysctl vars.
#  Duplicate keys get appended to existing values, and broken out again when
#  the file is written (does that even work?)

# This library exports several Errors, including
# FileMissing
#   Conf raises this error if create_if_missing == 0 and the file does not
#   exist
# IndexError
#   ConfShVar raises this error if unbalanced quotes are found
# BadFile
#   Raised to indicate improperly formatted files
# WrongMethod
#   Raised to indicate that the wrong method is being called.  May indicate
#   that a dictionary class should be written to through methods rather
#   than assignment.
# VersionMismatch
#   An unsupported file version was found.
# SystemFull
#   No more UIDs or GIDs are available
