Add isql-viewer 2.1.8, jDBC 2.x compliant database front end.
Submitted by: Stefan Schmidt <stefan.schmidt (at) stadtbuch.de>
Remark: isql-viewer depends on IBM's version (2.2) of BSF before it has
been donated to the Apache Software Foundation. Therefore this version
still uses the package name "com.ibm.bsf". In the current version of BSF,
the package name has been changed to "org.apache.org" to reflect the new
ownership. Thus, no separate port has been created to install this
dated version of BSF.
