 /*
-  The new login code explained
-  ============================
-
-  This code attempts to provide a common interface to login recording
-  (utmp and friends) and last login time retrieval.
-
-  Its primary means of achieving this is to use 'struct logininfo', a
-  union of all the useful fields in the various different types of
-  system login record structures one finds on UNIX variants.
-
-  We depend on autoconf to define which recording methods are to be
-  used, and which fields are contained in the relevant data structures
-  on the local system. Many C preprocessor symbols affect which code
-  gets compiled here.
-
-  The code is designed to make it easy to modify a particular
-  recording method, without affecting other methods nor requiring so
-  many nested conditional compilation blocks as were commonplace in
-  the old code.
-
-  For login recording, we try to use the local system's libraries as
-  these are clearly most likely to work correctly. For utmp systems
-  this usually means login() and logout() or setutent() etc., probably
-  in libutil, along with logwtmp() etc. On these systems, we fall back
-  to writing the files directly if we have to, though this method
-  requires very thorough testing so we do not corrupt local auditing
-  information. These files and their access methods are very system
-  specific indeed.
-
-  For utmpx systems, the corresponding library functions are
-  setutxent() etc. To the author's knowledge, all utmpx systems have
-  these library functions and so no direct write is attempted. If such
-  a system exists and needs support, direct analogues of the [uw]tmp
-  code should suffice.
-
-  Retrieving the time of last login ('lastlog') is in some ways even
-  more problemmatic than login recording. Some systems provide a
-  simple table of all users which we seek based on uid and retrieve a
-  relatively standard structure. Others record the same information in
-  a directory with a separate file, and others don't record the
-  information separately at all. For systems in the latter category,
-  we look backwards in the wtmp or wtmpx file for the last login entry
-  for our user. Naturally this is slower and on busy systems could
-  incur a significant performance penalty.
-
-  Calling the new code
-  --------------------
-
-  In OpenSSH all login recording and retrieval is performed in
-  login.c. Here you'll find working examples. Also, in the logintest.c
-  program there are more examples.
-
-  Internal handler calling method
-  -------------------------------
-
-  When a call is made to login_login() or login_logout(), both
-  routines set a struct logininfo flag defining which action (log in,
-  or log out) is to be taken. They both then call login_write(), which
-  calls whichever of the many structure-specific handlers autoconf
-  selects for the local system.
-
-  The handlers themselves handle system data structure specifics. Both
-  struct utmp and struct utmpx have utility functions (see
-  construct_utmp*()) to try to make it simpler to add extra systems
-  that introduce new features to either structure.
-
-  While it may seem terribly wasteful to replicate so much similar
-  code for each method, experience has shown that maintaining code to
-  write both struct utmp and utmpx in one function, whilst maintaining
-  support for all systems whether they have library support or not, is
-  a difficult and time-consuming task.
-
-  Lastlog support proceeds similarly. Functions login_get_lastlog()
-  (and its OpenSSH-tuned friend login_get_lastlog_time()) call
-  getlast_entry(), which tries one of three methods to find the last
-  login time. It uses local system lastlog support if it can,
-  otherwise it tries wtmp or wtmpx before giving up and returning 0,
-  meaning "tilt".
-
-  Maintenance
-  -----------
-
-  In many cases it's possible to tweak autoconf to select the correct
-  methods for a particular platform, either by improving the detection
-  code (best), or by presetting DISABLE_<method> or CONF_<method>_FILE
-  symbols for the platform.
-
-  Use logintest to check which symbols are defined before modifying
-  configure.ac and loginrec.c. (You have to build logintest yourself
-  with 'make logintest' as it's not built by default.)
-
-  Otherwise, patches to the specific method(s) are very helpful!
