A cluster of changes related to creating symlinks in the
/etc/{renames,repos}.d directories that point to the corresponding
README in sbopkg's docdir and then generally updating most
build-related files and getting it all documented.
* 50-default: renamed to 50-default.renames
* NEWS: note symlink docs and rename issues
* README-renames: update to reflect new default filename and the fact
that the files must end in '.renames'.
* sbopkg.conf.5, sbopkg.8: update to reflect the new renames stuff
(and the earlier repo file/dir-related changes I forgot to document
there).
* sbopkg: get_new_name(), get_old_name(): have grep only look through
*.renames files and not, say, symlinks to READMEs.
* doinst.sh: bring into alignment with the current SBo template.
* tools/sbopkg.SlackBuild: make links from README-repos and
README-renames to READMEs in the corresponding /etc/sbopkg/*.d
directories.
* tools/slack-desc: bring into alignment with the current SBo
template.
* tools/sspm: update address, add printe() and use it.
should still be customized by the user; add UID check; fix bug with
non-existent repo directories (thanks to Mauro for the even less buggy fix);
fix bug with a subshell that prevented sspm from exiting on one error - it was
meant to be a group command; convert the su block into a normal block; add a
couple more exclusions to the tar command to skip backup and tags files - and
throw a note into the ChangeLog so users don't get surprised by the repo
moving or having its ownership changed
