# copy.sh -- This function copies files inside the repository and
# updates menu, nodes and cross references inside repository
# documentation manual for each file copied.
#
# When a copying action is performed inside the repository,
# centos-art.sh script verifies whether the file being copied (the
# source file) is a regular file or a directory.
#
# When a regular file is the source of copying actions, the target
# location can be anything accepted by subversion copy command.
# However, when the source location is a directory, centos-art.sh
# verifies whether that directory is empty or not. If the directory is
# empty, then it is copied to target. However, when there is one or
# more files inside, centos-art.sh loops recursively through all files
# inside that directory, builds a list of files to process and copy
# file by file to target location creating parents directories for
# target files when it be needed.
