# unformat_parens.sh

|
# The manual pages before 2.10 treat format parentheses
|
|
# inconsistently. In some cases they are like
|
|
#
|
|
# .B name()
|
|
#
|
|
# while in others they are like:
|
|
#
|
|
# .BR name ()
|
|
#
|
|
# This script changes instances to the latter format.
|
|
# It does not fix all such instances: some will have to be
|
|
# done manually.
|
|
#
|
|
# Use the "-n" option for a dry run, in order to see what would be
|
|
# done, without actually doing it.
