[TLPSRC]... =head1 OPTIONS =over 4 =item B<--catalogue> I The I must point to a valid TeX Catalogue checkout; the default is C. If the directory is readable, the generated tlpobj files will contain information gathered from the TeX Catalogue. To disable this, specify a nonexistent filename, e.g., C<--catalogue=/nonesuch>. =item B<--fix-reverse-revisions> If a package with revisions going backward is found, this option makes C try to check in a dummy change to the package's tlpsrc file to artificially increase its version number. =item B<--from-files> Use C instead of C to create the list of files. =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<-n>, B<--dry-run> Don't make permanent changes: same as C<--no-commit> and C<--no-reverse-revision-check>, plus output to the C (if no C<--output> file is given) rather than updating the current tlpdb. =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<--no-commit> If changes have been made to the tlpsrc files (because reversed revisions have been found and C<--fix-reverse-revisions> is enabled) these changes will by default be committed using C on the tlpsrc directory. With this option the commit step is skipped. =item B<--no-reverse-revision-check> By default, C 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<--output=filename> By default, C saves/updates the tlpdb in the default place. This option specifies the place where the output should go to. =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 C<--from-files> option where the revision numbers will be adjusted afterwards by an external program. =item B<--tlpsrc-from-cmdline> By default, C recreates the tlpdb from all the tlpsrc files present in the current tree. If this option is given, the tlpsrc file(s), or package names, are given on the command line. If you're trying to debug the conversion of one particular package, this is the option to use (along with C<-n> and C<--catalogue=/nonesuch>, most likely). Indeed, if any non-option arguments are given, the program assumes you meant to specify this option. =item B<--with-w32-pattern-warning> Normally, this program issues a warning for patterns without a matching file, with the exception that it does I warn for binpatterns related to Windows. Giving this option makes it issue all warnings, i.e., also those where a W32-related binpattern does not hit. =back The standard options C<-q>, C<-v>, and C<-logfile>=I are also accepted; see the C function in L for details. =head1 DESCRIPTION C 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). This can happen when a file is removed and no other changes made. 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 is merged into the database (see L for the specifics). =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: #
