# Helper function for VCS_INFO_detect_*
|
|
#
|
|
# Usage:
|
|
# vcs_comm[detect_need_file]=FILENAMES VCS_INFO_bydir_detect DIRNAME
|
|
# where DIRNAME is a directory name and FILENAMES is a space-separated list
|
|
# of filenames.
|
|
#
|
|
# If any parent directory of the current working directory, other than the root
|
|
# directory, contains a subdirectory named DIRNAME that contains a file whose name
|
|
# is in FILENAMES, set vcs_comm[basedir] to the path of that parent directory and
|
|
# return true. Otherwise, return false.
