-In an effort to immediately correct any problems discovered in the
-originally shipped product, &company provides patches as a continued
-service to its customers.  To determine the current patch level of your
-&company software, a TECHINFO utility program has been provided.
-This program will display your current environment variables, the patch
-level of various &company software programs, and other pertinent
-information, such as your
-.fi AUTOEXEC.BAT
-and
-.fi CONFIG.SYS
-files.
-This information proves to be
-very useful when reporting a problem to the Technical Support team.
-.np
-To run TECHINFO, you must ensure the &company environment variable has
-been set to the directory where your &company software has been installed.
-TECHINFO will pause after each screenful of information.
-The output is also placed in the file
-.fi TECHINFO.OUT.
-.np
-Below is an example of some partial output produced by running the TECHINFO
-utility:

-In this example, the software has been patched to level "d".
-In most cases, all tools will share a common patch level.
-However, there are instances where certain tools have been patched
-to one level while others are patched to a different level.
-For example, the compiler may be patched to level "d" while the
-debugger is only patched to level "c".
-Basically, this means that there were no debugger changes in
-the D-level patches.

-If you run the TECHINFO utility, and determine that you are not at the
-current patch level, it is recommended that you update your software.

-Patches are available on &company's bulletin board, &company's FTP
-site and CompuServe.
-They are available 24 hours a day.
-Patches are also available on the current release CD-ROM.
-Each patch will include a batch file that allows you to apply the
-patches to your existing software.
-Note that patches must be applied in sequential order, as each patch
-depends on the previous one.
