# On STARTUP:
|
16 |
|
|
# 1. Options database (.Xdefaults on Unix or ? on Windows) is read
|
17 |
|
|
# 2. GDB prefs file is read ("gdbtk.ini" on Windows; ".gdbtkinit" on Unix)
|
18 |
|
|
# 3. GDB init script is read
|
19 |
|
|
#
|
20 |
|
|
# Normally all preferences will be set in the prefs file, which is
|
21 |
|
|
# a generated file. Hand-editing, if necessary, should be done to the
|
22 |
|
|
# GDB init script.
|
23 |
|
|
#
|
24 |
|
|
# when "save options" is selected, the contents of the
|
25 |
|
|
# preferences array is written out to the GDB prefs file.
