| 3 | dnl Test for the presence of a JDK. |

| 5 | dnl If "JAVA" is defined in the environment, that will be the only |
| 6 | dnl java command tested. Otherwise, a hard-coded list will be used. |
| 7 | dnl Similarly for "JAVAC". |
| 8 | dnl |
| 9 | dnl This macro does not currenly support testing for a particular |
| 10 | dnl Java version, the presence of a particular class, testing for |
| 11 | dnl only one of "java" and "javac", or compiling or running |
| 12 | dnl user-provided Java code. |
| 13 | dnl |
| 14 | dnl After AX_JAVAC_AND_JAVA runs, the shell variables "success" and |
| 15 | dnl "ax_javac_and_java" are set to "yes" or "no", and "JAVAC" and |
| 16 | dnl "JAVA" are set to the appropriate commands. |
