		Release notes-build software 1.2   (Jun 09)

	A compile-time definition for linux systems has been added for those
programs whose make files, etc can use them.

	A USEDATABASE environment variable will be defined if a user
so chooses.  See _build-env_.pl for a description of this variable

	Bug fix: make  build.pl clean  work



	When a web data page is displayed by the JGOFS system, there is
a link labeled "Plotting and Other Operations".  This link points to
a program located on a computer host called the "option server".
This version of build-env.pl redefines the name of that program
in order to a new logical operator.
	Except for these enhancements, the definition in old versions
of build-env.pl will continue to work.

	In the exceptional circumstances below, the newly
made modification will NOT work, and another definition is required.
1)	The build 1.1b definition points to a program on the option server 
   called "otheropt2".   The new definition is "otheropt3".  The new definition
   will NOT work unless the option server has a program named otheropt3.
   This program was added to the default option server (optserv1.whoi.edu)
   1 Jun 09.
2)	If the option server is in fact the default (optserv1.whoi.edu),
   then the new definition assumes that the JGOFS server 
   being built with build-env.pl is being built with at least version 3.2
   of a JGOFS software program called outer.
   	The packaging which includes this document is expected to include
   outer 3.2.  If the new build software is being retrofitted into an
   old data server, an older definition should be used.  The choices
   are "otheropt" and "otheropt2".  They are described in the build 1.1a
   readme file.

=========================

Installation issues:

	build-env.pl is  delivered as _build-env_.pl to avoid an 
accidental overwriting of an existing build-env.pl, which is 
likely to contain site-specific information.
	It is up to the installer to reconcile new, needed features from
_build-env_.pl into a "master" build-env.pl, which can be an onerous task.
It may be eased by noting that build-env.pl is divided into thirds by
2 lines of hash marks (###).  Most site-specific modifications will have
been made in the middle third.  Most modifications in new releases will
have been made in the first and last thirds.  Assuming no local
modifications outside the middle third, and unless noted elsewhere in
these release notes, a correct local version of build-env.pl can be
made by grafting the middle third of the current version of build-env.pl
over the middle third of _build-env_.pl and renaming _build-env_.pl
to be build-env.pl.  It's a good idea to back up the original
version of build-env.pl before doing the rename.
