# Look for function names inside \f[BI]...\f[PB] that aren't
|
|
# followed by "()".

|
|
# This script is designed to help with "by hand" tidy-ups after
|
|
# the automated changes made by add_parens_for_own_funcs.sh.
|
|
#
|
|
# The first argument to this script names a manual page directory where
|
|
# 'man2' and 'man3' subdirectories can be found. The pages names in
|
|
# these directories are used to generate a series of regular expressions
|
|
# that can be used to search the manual page files that are named in
|
|
# the remaining command-line arguments.
|
|
#
|
|
# Example usage:
|
|
#
|
|
# cd man-pages-x.yy
|
|
# sh find_slashes_no_parens.sh . man?/*.? > matches.log
