# cli_checkRepoDirSource.sh -- This function standardizes the path

# construction to directories inside the working copy, using absolute

# paths. This function transforms relative paths passed as non-option

# arguments to centos-art.sh script command-line into absolute paths

# inside the working copy. Further verifications, (e.g., whether they

# really exist as directories inside the working copy or not) should

# be realized outside this function. 

#

#   NOTE: Transforming relative paths into absolute paths before

#   processing them is very useful when you need to execute the

#   centos-art.sh script anywhere inside the workstation.

#

# Use this function whenever you need to be sure that non-option

# arguments passed to centos-art.sh script command-line will always

# point to directories inside the working copy.
