 * Revision history:
 *
 * 20190805 VE7FET 2.5.1
 * - Added missing variable substitution to rmschanstat/Makefile.am for 
 *   axports file location
 * - Fix install permissions on /etc/rmsgw/hooks scripts so they are 
 *   executable (they weren't)
 * - Basil already added updates to fix the path for SysopAdd in 
 *   winlinkservice.xml and add python-requests as a required package in 
 *   the Debian control file
 *
 * 20190119 VE7FET
 * - Refactoring code to use Autotools for building o improve portability
 * - Extracted hardcoded path/filenames, placed in pathnames.h and made 
 *   paths variable, depending on what is passed as sysconfdir variable 
 *   to ./configure script.
 * - Rename chantest to rmsgwchantest to make it more specific to this package 
 *   and install it by default (it was only built manually before, not so 
 *   good for packaging/building/installing the source automatically).
 * - Install the contrib scripts with the package docs in /usr/share/doc/rmsgw 
 *   or equivalent.
 * - Install the documentation to /usr/share/doc/rmsgw, or equivalent.
 * - On the first install, install the config files in /etc/rmsgw, or
 *   equivalent. On subsequent installs, if the config file already exists, 
 *   install the new file with a .dist suffix, so we don't clobber user 
 *   files on a upgrade.
