# Make dependencies on directories under which files are packaged.

# @RPMCONFIGDIR@/*-files.req.list file format:
# 1) Meaningful lines start with slash '/'.
# 2a) Each line must contain either one field: '<dir>';
# 2b) or two fields: '<dir> <pkg>'.
# In <dir>, trailing slash is ok.
#
# Whenever file path matches <dir> (that is, a file or directory
# is packaged under <dir>), this program prints explicit dependency
# on <dir>.  If file path matches a few directories, the longest-matching
# <dir> is printed.  Optional <pkg> name indicates that <dir> itself
# should be exclusively owned by <pkg>.
