# Prepare non-option arguments passed through the command-line for

# further processing.  When the argument provided is not an absolute

# path this function transforms it into an absolute path using the

# current working directory.

function tcar_checkWorkDirSource {

    local LOCATION=${1}

    # Append the current working directory when the location provided

    # isn't absolute.

    if [[ ! ${LOCATION} =~ '^/' ]];then

        LOCATION=${PWD}/${LOCATION}

    fi

    # Remove both consecutive slashes and trailing slashes from final

    # location. Remove dot-slash, as well.

    echo "${LOCATION}" | sed -r -e 's,/+,/,g' -e 's,/+$,,g' -e 's,\./,,g'

    # The single slash form doesn't point to repository's root

    # directory anymore. Instead, when a single slash is passed

    # as argument through the command-line, it preserves its regular

    # meaning which is pointing the workstation's file system.

    # The path verification isn't appropriate here because this

    # function is commonly used inside variable assignments and flow

    # control doesn't take place in such situation. In case path

    # verification fails here, the script wouldn't end its execution

    # which contradicts the expected behaviour.
