The QEF Quick Reference Card
	 
 User Setup
	+ Set $QTREE to Q-Tree directory tree to be used:
	    export QTREE=qtree-root (possibly `lclqtree`)
	+ Add $QTREE/bin to your $PATH
	    export PATH=$QTREE/bin:$PATH
	+ Define qd used to chdir using qds:
	    eval `qfunc qd` # add -c if using csh
	+ A useful function to edit a file from the source path:
	    eds() { $EDITOR $(sls $*) ; }
	+ To set up ~/.qtree directory:
	    dirsetup -d $HOME dotqtree
	+ To set up ~/.qtree directory with alternative name:
	    dirsetup -d $HOME -m .qtree=name dotqtree
	    export HOME_QTREE=$HOME/name
	 
 Documentation
	+ Manual pages are in $QTREE/man
	+ qefgui can be used to view man pages and x_db databases
	+ Every Q-Tree program has an -x flag that outputs synopsis,
	  one line description, summary of flags and options.
	+ quete or xdbs can be used to list or query x_db databases
	  xdbs will list available x-* databases
	+ www.qef.com contains The Guide and other documentation
	 
 Documentation Conventions
	+ topic(x-dbnm) refers to entry called topic in the x_db
	  database dbnm.  To access this topic use: x-dbnm topic
	+ @Variable refers to a qvrs variable.  For documentation on
	  such a variable use: x-qvrs Variable
	 
 Navigating the Forest
	Fields of a qdsrv path records:
	  Index Project Revision TreeType User Host Config Pathdirs ...
	qds selection flags (i.e., a path-spec):
	  -p project *; -r revision *; -t treetype **;
	  -u user *; -h host *; -c config
	  -num -- explicit path number
	  * use `.' for current value; automatically applied, if
	    necessary, unless the -a flag is specified.
	  ** -o == -tobject, -b == -tbaseline, -w == -tworking
	qds -b -pproj  # Find the baseline for project proj
	qds -u. -a  # Find all your paths
	qds -R  # Find the path of the current tree
	qdid -s123  # Bind user's qdid to a specific path (e.g., 123)
	qdid -s  # Bind user's qdid to the current tree
	qd -i  # chdir to current path bound to user's qdid identifier
	qd -I path-spec  # chdir to selected path and
	    simultaneously bind user's qdid to it
	qd -n  # chdir to next (i.e., parent) tree in current @RootPath
	qd path-spec subdir  # chdir to subdir of selected path;
	    use /subdir to choose directory relative to root
	qdmgt list -P  # list current projects in the database
	qdmgt -X  # list messages supported by qdsrv
	qdchk  # check user's paths on current host
	qhost host # check access to host and retrieve qtree and home
	 
 Setting Up Working and Object Trees
	qd -pproject -b  # chdir to project's baseline tree
	mkqtree -w working-dir [sub-dirs ...]  # create working
	    tree; use argument `.' to suppress creation of sub-dirs
	qd -pathnum  # chdir to new working tree
	mkqtree -o object-directory  # create an object tree
	treedirs [sub-dirs ...]  # create a tree's sub-directories --
	    defaults to all sub-trees.  If in object tree, defaults
	    to those sub-trees in the working directory.
	 
 Examining Your Current Configuration
	qvrs  # list current qvrs variables
	qvrs -f  # list current qvrs files
	qvrs -Pr  # output root.vrs
	qvrs -Pc  # output conf.vrs
	confvrs  # output settings by conf.vrs
	confvrs -d  # compare conf.vrs to default
	qvrs @Variable ...  # retrieve value of a qvrs variable
	qvrs -W Var ...  # list where qvrs variables set
	qvrs -l  # list library mapping controls
	qvrs -XI  # list cc -I flags
	qvrs -VD  # output value of @_DestDir_
	qvrs -V?  # output list of -V and -X short-cuts
	 
 Configuring Tree's root.vrs & conf.vrs
	rootvrs -d dir  # set _DestDir_
	rootvrs -A dir  # set RootAlias
	rootvrs -c conf  # set ConfigName
	rootvrs -B host  # set BuildHost -- use . for current host
	rootvrs -h sys  # name type of build system
	rootvrs -H  # equivalent to -h `system`
	rootvrs -u  # update current root.vrs from parent's root.vrs
	Note: Can use +Variable=value to set variable
	Note: Some settings may result in creation of new qdsrv path.
	      Use `qdmgt delete -number' to delete obsolete entry.
	qconfset -v V=Val  # add/change variable to conf.vrs
	qconfset -o Opt  # turn on option Opt
	qconfset -n Opt  # turn off option Opt
	 
 Reduced Qef -x
	qef [-x2cFkMntvX] [-A...] [-d dir] [-[DUGL]...] [-P process] [-f file]
		[-T {012}] [-m <num>] [args ...]
