HIERARCHICAL NOTEBOOK
	
	hierarchical notebook (hnb) is program to organise, many kinds of data
	in one place, for example addresses, to-do lists, ideas, book "reviews",
	brainstorming, organising a speech, making a  structured packing list 
	random notes, and probably many more I  haven't thought of yet..
	

HOW TO GET lhnb?
	http://nomi.cz/download/releases/lhnb/
	http://git.nomi.cz/?p=tomi/lhnb;a=summary

HOW TO GET hnb?
	new releases and information about hnb will appear at hnb's home page
	
	http://sourceforge.net/projects/hnb/
	
INSTALLING hnb
	if you've got a source release you must first compile hnb,..
	see further down in this file for instructions.
	
	Windows
		the windows binary distribution, is a .zip file	containing the
		executable, this README file, an sample database, and the 
		license for hnb's use. the binary is stand alone, so you can 
		just copy it wherever you'd like it to reside.
	Linux 
		the Linux binary distribution is a .tar.gz file	containing the
		executable, this README file, a an sample database, and the
		license for hnb's use. The binary is dynamically linked 
		against ncurses just place it anywhere in your path.. like
		/usr/bin, /usr/local/bin or /home/user/bin
		
COMPILING hnb
	
	hnb uses a custom Makefile, that should work on most unix'ish systems with a curses library.
	
	make
	su
	(enter root password)
	make install
	
	
USAGE DOCUMENTATION
	If you start hnb without any parameters and no default database, or
	with the -t or --tutorial option, hnb will load a special tutorial
	database.
	
CHANGELOG
	1.9.19
		new maintainer -- Tomas Janousek
		merged compile fixes from Fedora package
		merged a few things from Debian package (James Morrison)
			x86_64 fixes and todo in ps output
		fixed sorting of todo nodes
		added node expansion saving
		added overlong word wrapping
		added more intuitive node walking (go {,back}recurse-visible)
	1.9.18
		fixed segfault reported by thomas sattler, due to faulty handling of NULL input in node_get
		fixed segfault occuring when selecting the first menu item directly
		added autosave, and warning for concurrent sessions
		remove recovery file upon normal exit, when not in readonly mode
		from Terry Brown
			styles for child/not child on todo nodes
			parameter for expand to expand recursively
			new configuration variable add_at_top which causes nodes added when incremental search fails to be added at top when set to 1
		patch for xhtml compliance and automatic links for http:// urls, from Raphael Hertzog
		integrated debian patchset from James Morrison, including ability to expand subtrees
	1.9.17
		bug fix, when saving hnb DTD, I also saved the text attribute
		removed the format names from prefs.c,.. now the string specified is used instead, (makes extending easier)
		improved the tokenizer for libcli, it now acts almost exactly as bash, even the hooks for understanding $variable_expansion is included in the code, uses a single malloc
		various bug fixes
		cleanups and merging of commands, e.g. go_root, go_recurse, and go_backrecurse are now go <root|backrecurse|recurse|up|down|left|right>
		search now is a single command taking direction and query as arguments.
		changed escape to be the key used to bring up the menu,.. and remapped ^Q to be quit (again)
	1.9.16
		attempts to fix the compile on OSX
			renaming mergesort to node_mergesort due to nameclash
			only compiling the static lib
		made indent and outdent only work when there is no data typed already, (thus making > and < allowed typed in navigation mode as long as they're not the first character typed.
		removed errors appearing with -pedantic (at least here)
			removing all macros with variable arguments replacing them with va_list
			removing inline statements from libcli
		created an utility function for string replacements, that I inserted into all the various import/export filters.
		added a function "insert_cal <month> <year>" which inserts the specified month/year in a fashion that makes hnb useable as a simple timeplanner as well. (when I get around to adding support for clones, this might be interesting)
		allowing the user to use <,>,+ and - when typing in new data without erratic behavior, and not the need to enter edit mode. (except if it is the first char of the data)
		fixed an issue with creating the first child, and pressing insert, and various other commands,.. 
		added rpm spec file from Asgeir Nilsen
		made file_opml and file_hnb interpret all attributes
		implemented buffered reading for the xml tokenizer
		changed the function prototype for functions that register with libcli, they must now register with an int (int argc, char **argv, void *data) function
			overhauled hnb to use this API, some more refinement might be needed in someplaces, but it seems to work OK for now.
		added a menu that is accesed from F9
	1.9.15
		outdent fixed to be more efficient and work as intended
		added export context
		changed all import/export functions to use the query variable if filename passed is *
	1.9.14
		bugfix: The new sort and shuffle functions could result in dataloss when saved.
		new feature: expand/collapse and expand_all/collapse_all are new bindable functions, expand/collapse is bound to +/- in the default config file, they force portions of the tree to stay open even when you leave it.
	1.9.13
		Apparently I broke the nasty quick-sort I had implemented, when I changed the way the tree was stored. Implemented a Merge-sort which is faster anyways.
		Improved the behavior of non fixed navigation when the whole tree is displayed.
		Added a shuffle function (not currently bound), I used it while developing the new mergesort, but someone might find it useful.
	1.9.12
		Changed the datastructure to use a "assosciation list" for storing the actual data. Will move all tags, like checkbox to this structure.
			Should actually make it possible to do the addition of start end date and other "columns" a breeze, perhaps even automatic for some export/import formats
		modified tree_duplicate to use the new node_duplicate function, and a modified version of the import_node which takes a single node with data set as input.
		added import_node_text which disregards all other data items
	1.9.11
		changed node_swap to only swap relational pointers, thus making it easier to extend the data stored in Node later
			thus also changing and move node, indent/out-dent and sort to accommodate for a truer swap
		fixed a bug with editing of newly introduced child
			note: should perhaps move ui_action_edit into a built-in command that is handled specially since it now needs special attention by being a subcommand to ui_action_command
	1.9.4-1.9.10 feb 2003
		re-implementation of positioning of selection bar in non fixed mode
		massive code cleanup and separation
		separation of variables from prefs.* to static variables in the code modules where they belonged
