Debug tools
|
||||||
|
-----------
|
||||||
|
|
||||||
|
This directory contains a few tiny programs that may be helpful when
|
||||||
|
debugging LZMA Utils.
|
||||||
|
|
||||||
|
These tools are not meant to be installed. Often one needs to edit
|
||||||
|
the source code a little to make the programs do the wanted things.
|
||||||
|
If you don't know how these programs could help you, it is likely
|
||||||
|
that they really are useless to you.
|
||||||
|
|
||||||
|
These aren't intended to be used as example programs. They take some
|
||||||
|
shortcuts here and there, which correct programs should not do. Many
|
||||||
|
possible errors (especially I/O errors) are ignored. Don't report
|
||||||
|
bugs or send patches to fix this kind of bugs.
