+Introduction
+.PP
+A number of new specialized image reduction packages and new versions
+of the generic echelle and multiobject spectroscopy packages have been
+added to the \fBimred\fR package in IRAF Version 2.10.  The new
+subpackages will be made available as external packages prior to
+the release of V2.10.  The major changes are:
+
+.IP \(bu
+New multifiber reduction packages \fBargus\fR, \fBnessie\fR, and
+\fBkpcoude.fiber\fR.
+.IP \(bu
+New spectrophotmetric slit spectra reduction packages \fBgoldcam\fR,
+\fBspecred\fR, and \fBkpcoude.slit\fR.
+.IP \(bu
+New versions of the \fBmsred\fR and \fBechelle\fR packages based on
+the new versions of \fBapextract\fR and \fBonedspec\fR.
+
+.LP
+In additions there have been some minor changes in the other
+spectroscopy packages required by changes in the \fBonedspec\fR package.
+.PP
+The new packages are specialized to specific instruments or types of
+data.  They contain tasks collected from the various general spectroscopy
+packages which are appropriate for a particular type of data.
+However, the most important contribution of these packages are
+special reduction tasks which are streamlined to perform the complete
+calibration and reduction of the data in as simple and automated
+manner as possible.  The tasks combine operations from both two
+dimensional extraction and one dimensional spectral calibrations
+and collects all the useful parameters in two parameter sets while
+fixing and hiding parameters which are irrelevent.
+.PP
+The new packages are as follows.  The \fBargus\fR package is for the
+flat fielding, throughput correction, extraction, dispersion correction,
+and sky correction of data from the CTIO \fIArgus\fR multifiber instrument.
+The \fBnessie\fR package is similar and is for the KPNO \fINessie\fR
+multifiber plugboard instrument.  The \fBkpcoude.fiber\fR package is
+specialized for the three fiber (two arc and one object) instrument
+at the KPNO Coude.  It is similar to the other multifiber packages
+except there is no sky subtraction.
+.PP
+The other three packages are for sky subtracted extraction,
+dispersion correction, extinction correction, and flux calibration
+of slit instruments.  The packages are for the KPNO \fIGoldcam\fR,
+the KPNO Coude, and for the CTIO \fI2DFRUTTI\fR.  They are all
+fairly general and could be used for other instruments.  They are
+distinguished by choices of default parameters.
+.PP
+There are user's guides for the powerful new reduction tasks in
+the new packages.  These are available both as nicely typeset
+documents and as on-line IRAF manual pages.
+.PP
+Tasks from the revised \fBapextract\fR and \fBonedspec\fR packages
+appear in many of the \fBimred\fR packages.  In particular the
+\fBechelle\fR and \fBmsred\fR packages are now based on this new
+software.
+.PP
+Some minor changes are the replacement of the \fBspecphot\fR package
+by \fBspecred\fR and the renaming and reorganization of the
+\fBcoude\fR package.
