[TLPSRC]... =head1 OPTIONS =over 4 =item B<-catalogue> I The location given by B<-catalogue> must point to a valid TeX Catalogue. No default value. If given, the generated tlpobj files will contain information gathered from the TeX Catalogue. =item B<-master> I The location I must point to a valid svn repository of TeX Live's Master directory. Defaults to C<../..> of C<$0>. =item B<-no-bin-split> Do NOT split files with binaries into several packages (one for the arch independent and one for each of the architectures with only the respective binaries). There is no reason to use this option. =item B<-tlpsrc-from-cmdline> by default, B recreates the tlpdb from all the tlpsrc files present in the current tree. If this option is given the tlpsrc have to be given on the command line. =item B<-output=filename> by default, B saves/updates the tlpdb in the default place. This option specifies the place where the output should go to. =item B<-with-win-pattern-warning> Normally, this program issues a warning for all patterns without a matching file, but does I warn for binpatterns when working on the win32 architecture. Giving this option makes it issues all warnings, i.e., also those where a binpattern on win32 does not hit. =item B<-from-files> Use find instead of svn -status to create the list of files. =item B<-no-revision-check> By default, B checks that in the generated tlpdb the revision numbers of packages are not going backward compared to the previous version. This option disables this check. =item B<-fix-reverse-revisions> If a package with revisions going backward is found, this option makes tl-update-tlpdb try to check in some dummy changes to the package's tlpsrc file to artificially increase the version number. =item B<-no-commit> If changes have been made to the tlpsrc files (because reversed revisions have been found and B<-fix-reverse-revisions> was given) these changes will by default committed using C on the tlpsrc directory. Giving this option the commit step is skipped. =item B<-save-anyway> If the newly created tlpdb is in considered buggy due to reversed revisions it will normally not be saved. This switch allows saving it anyway. It can be useful in combination with the B<-from-files> option where the revision numbers will be adjusted afterwards by an external program. =back The standard options B<-q>, B<-v>, and B<-logfile>=I are also accepted; see the C function in L for details. =head1 DESCRIPTION B converts TeX Live source package files (tlpsrc) files into a TeX Live package database (tlpdb). In addition if at the same location there is already a TLPDB, it compares the revision number of packages and checks if a package is going back in time (i.e., having a smaller revision number in the new tlpdb). In this case it commits a dummy change to the package's tlpsrc file to make sure that revisions are always increasing. If a TeX Catalogue hierarchy is specified, additional information from the catalogue are merged into the database (see L for the list of included information from the TeX Catalogue). =head1 AUTHORS AND COPYRIGHT This script and its documentation were written for the TeX Live distribution (L) and both are licensed under the GNU General Public License Version 2 or later. =cut ### Local Variables: ### perl-indent-level: 2 ### tab-width: 2 ### indent-tabs-mode: nil ### End: # vim:set tabstop=2 expandtab: #
