Abstract:
|
||
|
|
|
||
|
|
This is the main source file for the SPLITSYM utility program. This
|
||
|
|
program can be used to split the debugging information contained in
|
||
|
|
an executable image file into a separate .DBG file and strip it from
|
||
|
|
the image file. Allow stripped image files to be distributed which
|
||
|
|
significantly reduces disk space requirements, but allows full
|
||
|
|
debugging by accesing the associated .DBG files over the network
|
||
|
|
when needed.
