xplain2sql converts files from Xplain to SQL. It supports a very large subset of Xplain, and it can convert from Xplain to Microsoft SQL Server, DB/2, Inprise InterBase, PostgreSQL, Oracle, MySQL 5, SQLite 3 or ANSI-92 SQL. It can also generate an XML description of the generated SQL. This XML description can be used to create low-level middle-tier code. Example stylesheets for Eiffel/ECLI and Delphi/ADO are included. The C source code release should compile on any platform with an ANSI C compiler. There are binary releases for FreeBSD, Linux, Solaris x86, and Windows 2000.
xps dynamically displays in an X Window the Unix processes as a tree or forest, the roots on the left and the leaf processes on the right. The status of each process (running, sleeping, stopped, etc.) can be indicated by a color. Different users appear as different colors. Process selection can be made per user, all users or through a regular expression pattern. A process can be selected to show ps information or to send the process a signal.
