	in the history of pbctools, refer either to NEWS or to the git
	log.

2010-04-26  Olaf Lenz  <olenz@qwghlm>

	* pbcjoin.tcl: Small fix to allow pbc join to be used on several
	frames in one command.

2010-04-21  Olaf Lenz  <lenzo@pckr97.mpip-mainz.mpg.de>

	* pbcwrap.tcl: Reintroduced Tcl code (get_connected) to determine
	connected compounds that contain all atoms that are
	connected ("fragment" only does this if all atoms are in the same
	segment and chain).

	* pbcjoin.tcl: Added compound type "connected". Extended verbosity.

2010-02-16  Olaf Lenz  <olenz@qwghlm>

	* pbctools.tcl: Fixed email address of olenz.

	* pbcwrap.tcl: Added compound type "fragment".

2009-11-04  Olaf Lenz  <olenz@qwghlm>

	* pbcset.tcl: Incorporated Jan Saams commits to the VMD CVS, log
	message:
	Fixed a bug reported by Olaf Lenz:
	> % pbc readxst kiley.xst -alignx
	> atomselection move:: need a 4x4 matrix
	Now xst files containing PBC vectors that don't follow the
	standard alignment (A||x, B in x-y plane) are read and the
	molecule is aligned accordingly when using -alignx option.
	Fixed indentation in a few places.

2009-10-09  Olaf Lenz  <lenzo@pckr97.mpip-mainz.mpg.de>

	* doc/pbctools.tex (subsection{\texttt{set}}): Fixed small error
	in the documentation of "pbc set", thanks to Axel Kohlmeier and
	Lan He.

2009-06-26  Olaf Lenz  <lenzo@pckr97.mpip-mainz.mpg.de>

	* doc/pbctools.tex: Added note that -centersel only has an effect
	when -center bb/com is used. Thanks to Alberto Sergio Saray.

2009-05-14  Olaf Lenz  <olenz@qwghlm>

	* pbctools.tcl: Applied Axel Kohlmeyer's docfix patch.

	* doc/pbctools.tex: Restructured introduction, abstract and basic
	usage section.

	* pbcjoin.tcl (pbcjoin): Added option "-[no]border", which allows
	to specify the maximal depth were atoms of a broken compound can
	be found inside the unit cell. Currently works only for orthorhombic
	unit cells.

	* pbcwrap.tcl (pbcwrap): "-center" now understands a selection as
	argument again, for backward compatibility. However, a deprecation
	warning is printed.

2009-05-11  Olaf Lenz  <olenz@qwghlm>

	* pbcjoin.tcl (pbcjoin): Some more improvements, added more
	detailed progress report.

2009-04-30  Olaf Lenz  <lenzo@pckr97.mpip-mainz.mpg.de>

	* pbcjoin.tcl (pbcjoin): Some more improvements to "pbc
	join". Im my tests, I got a performance gain of about 50%.

2009-04-23  Olaf Lenz  <olenz@qwghlm>

	* pbcjoin.tcl: Thanks to Dan Lussier: significantly reduced memory
	footprint of "pbc join".

2009-02-10  Olaf Lenz  <olenz@true>

	* pbcjoin.tcl: Thanks to Axel Kohlmeyer, join now checks whether the pbc cell
	parameters are reasonable.

	* pbctools.tcl: Added implementation of vmdcon for VMD version
	before 1.8.7.
	
	* *.tcl: All functions use vmdcon now instead of "puts".

2009-01-21  Olaf Lenz  <olenz@true>

	* Advanced to version 2.5.

	* pbcbox.tcl, pbcwrap.tcl, pbctools.tex: Commands pbcwrap and
	pbcbox: Added option "-centersel" that takes a selection. The
	option "-center" does not take the $sel argument anymore, instead
	the keywords "com", "centerofmass", "bb" or "boundingbox" can be
	used to denote that the center of the box/wrapping is in the
	center of mass or the center of the bounding box of the given
	selection.

2008-11-20  Olaf Lenz  <lenzo@pckr76.mpip-mainz.mpg.de>

	* Advanced to version 2.4.
	
	* maintainer/: Added maintainer directory that contains scripts
	and notes for the maintainer.

	* pbcwrap.tcl, pbcunwrap.tcl, pbcjoin.tcl: Added option
	"-noverbose" for completeness.

	* doc/index.html: Now contains only link to the pbctools gfroge
	home page: http://www.espresso-pp.de/projects/pbctools/ 
	
	* doc/pbctools.tex: Translated doc/index.html to LaTeX.

2008-10-27  Olaf Lenz  <olenz@true>

	NEWS and AUTHORS file in the future.

	docs and credits.

	* Advanced to version 2.3.

	* pbcbox.tcl, pbcwrap.tcl: Renamed option -rectangular to
	-orthorhombic (-rectangular still works).

2008-06-14  Olaf Lenz  <olenz@qwghlm>

	and implementation by VMDs native "fragment".

2008-06-10  Olaf Lenz  <olenz@qwghlm>

	* pbcwrap.tcl, pbcjoin.tcl: Bugfix: "pbcwrap -compound segment"
	didn't work: Used wrong keyword "segment" for segment selection,
	instead of "segid". Reported by Chris Maffeo <cmaffeo2@uiuc.edu>.

	* pbcwrap.tcl, pbcunwrap.tcl, pbcjoin.tcl: Added -verbose option
	to wrap, unwrap and join. 

	* pbcset.tcl: Added -check option to pbcget: checks the cell
	parameters for validity.

	* pbcunwrap.tcl: Use generic function from pbcwrap.

	* pbcwrap.tcl: Added generic pbcwrap_coordinates function to wrap
	coordinates into a unit cell around another coordinate.

	* pbcjoin.tcl, pkgIndex.tcl, doc/index.html: First implementation
	of pbc join.

	* pbcjoin.tcl: Added. Will contain a function to join wrapped atom
	compounds.
