294

|
|
295

|
|
|
|
|
|
A debugger is a computer program that is used to debug other |
296
|
|
|
|
|
|
|
programs. L<Devel::ebug> is a simple, extensible Perl debugger with a |
297
|
|
|
|
|
|
|
clean API. L<Devel::ebug::HTTP> is a web-based frontend to L<Devel::ebug> which |
298
|
|
|
|
|
|
|
presents a simple, pretty way to debug programs. L<ebug_http> is |
299
|
|
|
|
|
|
|
the command line program to launch the debugger. It will return a URL |
300
|
|
|
|
|
|
|
which you should point a web browser to. |
