# make

If compilation produces errors, or a large number of warnings,
please read README.COMPILATION.PROBLEMS -- you might be able to
adjust the flags in this Makefile to improve matters.

Also in README.COMPILATION.PROBLEMS are some hints that may help
if your build produces an executable which is unable to correctly
handle so-called 'large files' -- files of size 2GB or more.

If you got this far and the 'cmp's didn't complain, it looks
like you're in business.

To install in /usr/local/bin, /usr/local/lib, /usr/local/man and
/usr/local/include, type

   make install

To install somewhere else, eg, /xxx/yyy/{bin,lib,man,include}, type

   make install PREFIX=/xxx/yyy

If you are (justifiably) paranoid and want to see what 'make install'
is going to do, you can first do

   make -n install                      or
   make -n install PREFIX=/xxx/yyy      respectively.

The -n instructs make to show the commands it would execute, but
not actually execute them.

Instructions for use are in the preformatted manual page, in the file
bzip2.txt.  For more detailed documentation, read the full manual.
It is available in Postscript form (manual.ps), PDF form (manual.pdf),
and HTML form (manual.html).

You can also do "bzip2 --help" to see some helpful information.
"bzip2 -L" displays the software license.
