# Known issues:

|

|
|
# Future enhancements:
|
||
|
|
# - check if the value assigned to all known keys are valid. this can
|
||
|
|
# be done by having a hash having {<key> => <regex-to-check>} pairs
|
||
|
|
# for each key to check.
|
||
|
|
# e.g. { 'DHCP' => 'yes|no' }
|
||
|
|
# - check syntax of entries in the [NetBindings] section.
|
||
|
|
# - check for empty values that will cause winnt32 to croak
|
||
|
|
# e.g. key=
