7 # AC_CHECK_DOCBOOK_DTD([dtd-version])
11 # Check for access to a docbook DTD of a particular revision. This macro
12 # can be used for multiple versions within the same script.
16 # $1 is the version of docbook to search for; default 'current'.
20 # $HAVE_DOCBOOK_DTD_VERS will be set to 'yes' or 'no' depending on the
21 # results of the test, where VERS is $1, with '_' substituted for '.'
22 # $HAVE_DOCBOOK_DTD will also be set to the same value.
26 # AC_CHECK_DOCBOOK_DTD(4.3)
27 # if test "x$HAVE_DOCBOOK_DTD_4_3" = "xyes"; then
