- # 1. Remove everything above the #! /bin/sh line.
- # 2. Save the resulting text in a file.
- # 3. Execute the file with /bin/sh (not csh) to create:
- # README
- # diff

- XThis directory contains a diff for a modified version of the lex driver
- X(ncform). It is not absolutely necessary to cake: the only difference
- Xis in error detection. If you cannot or do not want to install this diff
- Xto ncform, (e.g. cause you have an unsymphatetic root or you are worried
- Xabout AT&T's copyright on the original ncform, of which this one is a
- Xsmall modification), you should keep the calls to and the definition of
- Xcheck_actlen in cake_s.l; otherwise you should comment them out.
- X
- XCatching lex buffer overflows is important. Some cake actions, like
- Xmake actions, are very long, but this may not be apparent, as this
- Xlength would almost certainly result from macro expansion (a link
- Xcommand for a large system can easily reach hundreds of bytes).
- XAn overflow like this, if it occurs, leads to core dump, and the bug
- Xcan be VERY HARD to track down. I know, I spent a week on it once.
