# Merge two clamd.conf or freshclam.conf files and write the result to
|
||
|
|
# the standard output. The result file contains all comments from the
|
||
|
|
# second file with the active (i.e. not commented-out) settings from
|
||
|
|
# the first file merged into it. Settings which were only in the first
|
||
|
|
# file file and not mentioned in the second file any more, are appended
|
||
|
|
# at the end, but commented out.
|
||
|
|
#
|
||
|
|
# Any comment must start with a hash and a space:
|
||
|
|
# # comment
|
||
|
|
# while any commented out setting must start with a hash and no space:
|
||
|
|
# #settingname settingvalue

|
|
#
|

|
|
# The first file may optionally have the format that was used up to
|
||
|
|
# version 0.88.7. In that case the settings will be converted to the
|
||
|
|
# format that is used in version 0.90 and newer.

# Known issues:

|
|
#
|
||
|
|
# If an option exists more than once in eiter file, only the first
|
||
|
|
# occurance will be moved over from the first file. AFAIK this
|
||
|
|
# currently only applies to the DatabaseMirror option in
|
||
|

# freshclam.conf.
