# cli_checkRepoDirSource.sh -- This function standardizes the access

# 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 and verifies whether they really exist as directories

# inside the working copy or not. If the path provided doesn't exist

# as directory inside the working copy, the script will finish its

# execution immediately with an error message. Otherwise, if the

# directory exists, the variable ACTIONVAL is redefined with the

# related absolute path for further use.

#

#   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.
