create a source tarball, a documentation tarball if a doxygen module is

detected, and will also attempt to sign the tarballs with gpg (although

it is not a fatal error if this step fails).

Upgrading build system
|
||||
----------------------
|
||||
|
||||
Sometimes, the nonvolatile parts of the build system (the static parts
|
||||
that are committed to the repository) need to be upgraded as well. There
|
||||
is a script to do this in the lw-build-system repository.
|
||||
|
||||
From the project base directory, run the script
|
||||
`/path/to/lw-build-system/update.sh'. This only works if symlinks are
|
||||
installed. It will create a patch file, which you should edit before
|
||||
applying.
|
||||
|
||||
Unfortunately, the upgrade process is not perfect and will not detect
|
||||
legitimate changes you have made to files such as `config' and modules'
|
||||
`build.*' files. You will need to manually edit the patch to revert
|
||||
false positives.
