| 3 | You need the parser generator CUP v0.10j (or newer) for the parser to work.
|

| 4 | Use the Makefile to generate the lexer and parser, or type:

| 7 | jflex java.flex

| 9 | javac JavaParser.java TestLexer.java
|

| 12 | The parser can be tested with:
|
|---|
| 13 | java JavaParser <inputfiles>
|
|---|
| 14 |
|

| 15 | The scanner (without parser attached) can be test with:
|
|---|
| 16 | java TestLexer <inputfiles>
