pfstools 1.2.1 <19.07.2005>
         * bug fixed: seg fault in pfsoutexr and pfsabsolute
	 * bug fixed: pfsin uses bash as a shell
	 
pfstools 1.2 <15.06.2005>
	 pfs library: extended api:
	 * pckconfig file renamed from pfs-1.0.pc to pfs.pc
	 * iterator over all tags in TagContainer
	 * new iterator over all channels in Frame
	 * FrameFileIterator can be used together with getopt and getopt_long
	 pfsinexr, pfsoutexr: can read/write all channels and all tags/attributes
	 added: pfsinpfm, pfsoutpfm - to read/write PFM HDR images
	 pfsin*,pfsout*: now use 'LUMINANCE' tag to keep the track of the type of
	                 intensities stored in the pfs stream:
			 relative (linear) or display (gamma corrected)
	 pfssize: new arguments --minx, --miny, --maxx and --maxy
	 pfs library: sRGB color space scaled to keep channel values
	   within 0-1 range (to be compliant with the other parts of pfstools)
	 Added new filters
	 * pfscut - crops images
	 * pfscat - concatenates images or animations
	 * pfspad - add border to images or animations
	 * pfsrotate - rotates images by 90deg
	 * pfsflip - flips images
	 * pfsabsolute - calibrates images to absolute units (Y in cd/m^2)
	 Support for LUMINANCE tag (recognized by some pfsin* and pfsout* commands)
	 
pfstools 1.1 <29.01.2005>
	pfsview: minimum and maximum of the luminance window can be
	  dragged (previously only entire window could be dragged)
10.01.2004
	added: support for gcc 3.4.2 (thanks to Fabio Mierlo)
15.12.2004
        added: pfspanoramic
05.12.2004
	pfsview: optimized mapping function for faster display and
	better responsiveness
	pfsview: added visualization of negative values
	pfsview: added option to switch off NaN and Inf marking
	pfssize: fixed problem with boundary conditions
	pfsview: shortcuts added
24.11.2004
	added: octave script: pfssize
	transformColorSpace does graph traverse to find conversion
	between any color spaces
18.11.2004
	pfsview: can save visible window as .png image
17.11.2004
	pfsextractchannels: added
	Updated man pages
02.11.2004
	pfsview: it is now possible to move back and forth between the frames
	pfsin*: all those commands now add a tag FILE_NAME 	
27.10.2004
	Rewritten and much improved pfssize. Enlarging of images is now
	possible. pfssize rewrites tags to the resized stream.
