Version 3.5.6 (July 9, 2008)
Fixed subroutine call in FIBAREA so it compiles on Macs
Use local sorting subroutines in HSKYMATCH

Version 3.5.5 (April 14, 2008)
Add HSETGAIN and HRESETGAIN to stop and start reading gain from header GAIN keywords

Version 3.5.4 (March 6, 2008)
New HSPROC task processes data for one pointing from raw through sky subtraction
Add HRELEARN to add new parameters when updated
Add merge, perchip, flatten, normfile parameters to HPROC
Optionally add HMERGE1 to HPROC to complete multi-extension processing
Add HPREAMP1, HPROC1, HGAIN1 to process single images
Add optional HMERGE1 (don't merge bias and dark) to HPROC
Add optional HFLAT1 (don't flatten bias, dark, flats before MAKEFLAT) to HPROC
Revise gains in HPROC, GAINCORR and HGAIN1 after Nelson Caldwell recomputed them

Version 3.5.3 (November 5, 2007)
Add t_preamp1.x to replace C computation of preamplifier fix. It is called by hpreamp.cl, which is called by hproc.cl.

Version 3.5.2 (October 15, 2007)
Add redleak paramter to htran to turn off call to hredleak1 for spectra which are too blue to see the red leak.

Version 3.5.1 (September 26, 2007)
Added parameter to hskyproc and hskylist so objects can be chosen to be on one chip or the other and fixed a bug in hskyproc so that the correct sky database is used when using skysame is no.
Upped maximum number of lines from 4608 to 4700 in hcosbad.x and hcoslim.x
Add debug parameter to hcosbad

Version 3.5.0 (September 12, 2007)
hskyproc, hskylist, hskyfilt, hskyfind, and hskysub1 CL scripts and
hskymatch SPP task added to replace skyproc ksh script to remove
background from spectra

Version 3.4.1 (June 1, 2007)
Add hsmapfix172 and hsmapfix222 to set broken fiber apertures to unused

Version 3.4 (May 22, 2007)
Add hcosmic + hcoslim + hcosbad tasks to remove cosmic rays froms spectrum images before extracting spectra. hscombine then sums instead of averaging or medianing.

Version 3.3 (December 19, 2006)
Add haphead task to compute fiber area and set header values from APID
Rewrite hsplit so almost everything is done in SPP tasks instead of CL

Version 3.2 (November 20, 2006)
Add hrefit task to remove sky background from multispec files
Add fitmax, apobj, and apsky parameters to hskyfit1 to work with SVDFIT 1.6

Version 3.1 (November 14, 2006)
Use internal parser instead of IRAF's in t_imgetp.x
Add fibarea task to compute area of fiber at specific focal plane location

Version 3.0 (August 17, 2006)
Add Bill's SPECROAD and supporting shell scripts in directory Shell
Add Maureen's freidentify task
Update hsplit to use scopy to break off individual spectra
Other changes to ease processing of Hectochelle data

Version 2.7 (March 3, 2006)
Add skyfit1 task to fit and remove sky background from spectra using svdfit package
New skyproc task includes fit sky removal using svdfit package via skyfit1
New resub task to try different sky removal methods
Lots of other changes, too

Version 2.6 (October 24, 2005)
Add hback and hback1 to remove background from all spectra in a multispec file
These scripts can be used to flatten the background of a calibration lamp spectrum

Version 2.5 (August 15, 2005)
Make single-file versions of all pipeline scripts
Group pipeline scripts into master scripts (hlin, htran)

Version 2.3 (March 2, 2005)
Fix bug in hgeom.cl so file names without .fits work
Add Bill Wyatt's redleakcorr.cl and doredleak.cl tasks
