Erni updates

As of release 0.50.0 (2004/06/08)

- Erni will optionally fork() to run the specified
  command in a child process

- Erni's logging subsystem has been completely
  rewritten

- Having long since outgrown its single source file
  (kept to make it a dropin replacement for Titan's
  "runas"), the code was split into four modules.

- Releases now follow a more Apache-style numbering:
  a release number simply denotes a given code base,
  which is promoted from alpha -> beta -> stable
  through testing.  (e.g. the 0.50.0 codebase is 
  initially released as an alpha; if no bugs are
  discovered, its status is changed to "stable"
  without any change to the number or source packages.)

As of release 0.41.0 (2003/10/10)

- Erni now supports supplementary group memberships, 
  both default (i.e. loaded from /etc/group or the 
  system's networked equivalent) and user-specified 
  (i.e. on the commandline).

	* to use default groups, don't specify any groups on 
	  the commandline:

			erni -u {user}

	* to explicitly set multiple group memberships, pass
	  a comma-separated list of names on the commandline:

			erni -u {user}:{group1},{group2},...,{groupN}
		

- A memory bug that was causing select coredumps under
  Solaris has been resolved.

As of release 0.31.0 (2003/09/25)

- cleaned up the commandline arg passing:
	* umask ("-m") is no longer required; there is a 
	  default value of "027."

	* group ("-g") has been merged with user ("-u")
	  for more of a chown-style interface of "user:group".
	  As both parameters are so closely related, and 
	  required, it makes better form to specify them 
	  together.
  
- Erni is now available as an RPM, for those using
  RPM-based Linux distros.

As of release 0.30.1 (2003/07/09)

- Fixed a bug which impaired the -E option. Erni now
  properly processes commandlines, including flags, 
  when passed after -E.
