# 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.
