Installing cppawk
-----------------

A cppawk installation consists of the cppawk script accompanied by the
an include directory containing the cppawk headers.

cppawk determines the directory in which it is located, calling that
directory selfdir. Then it instructs the preprocessor to look for
headers in $selfdir/../share/cppawk/include. For instance, if cppawk is
installed as /usr/local/bin/cppawk, it expects its header library to be
in the /usr/local/share/cppawk/include directory.

Steps to install cppawk as /path/to/installation/cppawk/bin might be:

# root=/path/to/installation
# install -d ${root}/bin
# install -d ${root}/share/cppawk/include
# install cppawk ${root}/bin
# install share/cppawk/include/*.h ${root}/share/cppawk/include

Historic note: originally, cppawk expected the include direcgtory
to be called cppawk-include, and to be located in the same directory
as itself.
