哪位大俠能幫忙把下面這段代碼給逐一解釋一下？
謝謝！
{ echo "$as_meLINENO: checking whether to use apache2 as server transport" >&5
echo $ECHO_N "checking whether to use apache2 as server transport... $ECHO_C" >&6; }

# Check whether --with-apache2 was given.
if test "${with_apache2+set}" = set; then
  withval=$with_apache2;  case "$withval" in
  no)
    { echo "$as_meLINENO: result: no" >&5
echo "${ECHO_T}no" >&6; }
    APACHE2BUILD=""
    ;;
  *)
    { echo "$as_meLINENO: result: yes" >&5
echo "${ECHO_T}yes" >&6; }
        if test -d $withval; then
        apache2inc="-I$withval"
        elif test -d '/usr/include/apache2'; then
        apache2inc="-I/usr/include/apache2"
    else
        { { echo "$as_meLINENO: error: could not find apache2. stop" >&5
