<simple install procedure>

First of all, unpack the tar ball in an appropriate directory (say, ~/tmp).

	% tar xvfz xhangglider-0.90a.tar.gz

Change to its toplevel directory.

	% cd xhangglider-0.90a

Run xmkmf to create the Makefile.

	% xmkmf

After the Makefile is created, run make and build xhangglider.

	% make

 If unfortunately building fails, try to edit Imakefile or Makefile 
(sometimes .c files, too) and run make again. If you don't understand what is
wrong, ask some hackers around you or send me an e-mail for the answer.
 If the build is successful, become superuser (if necessary) and type as below 
to install:

	# make install
	# make install.dat

If you don't understand the word 'superuser', or an error message like
'permission denied' appears, you should read the following:

<tip>

 You can install xhangglider into your home directory, too. To do so, you need
a little modification to some files.

 Modify the lines of the file 'Imakefile' from

	DATDIR = /usr/local/share/xhangglider
	BINDIR = /usr/local/bin

to
	
	DATDIR = $(HOME)/xhang
	BINDIR = $(HOME)/xhang

Possibly you need no more modification. It's easy, isn't it ? Then, type

	% xmkmf
	% make
	% make install
	% make install.dat

and you can install xhangglider to your home directory. Type this to run
the program:

	% ~/xhang/xhangglider

Enjoy!
