The utility needs to be invoked\nfrom the top directory of the old source code directory, and if a relative name is given for\nthe new archive or patch file, it will be looked for first relative to the execution direc‐\ntory and then relative to the parent of the source tree. (For example, if the changelog file\nis /usr/local/src/foo/foo-1.1/debian/changelog, then the archive or patch file will be looked\nfor relative to /usr/local/src/foo.) Note that the patch file or archive cannot be within\nthe source tree itself. The full details of what the code does are given below.\n\nCurrently supported source code file types are .tar.gz, .tar.bz2, .tar.Z, .tgz, .tar,\n.tar.lzma, .tar.xz, .7z and .zip archives. Also supported are already unpacked source code\narchives; simply give the path of the source code directory. Supported patch file types are\ngzip-compressed, bzip2-compressed, lzma-compressed, xz-compressed and uncompressed patch\nfiles. The file types are identified by the file names, so they must use the standard suf‐\nfixes.\n\nUsually uupdate will be able to deduce the version number from the source archive name (as\nlong as it only contains digits and periods). If that fails, you need to specify the version\nnumber explicitly (without the Debian release number which will always be initially “1”, or\n“0ubuntu1” on Ubuntu-detected systems). This can be done with an initial --upstream-version\nor -v option, or in the case of an archive, with a version number after the filename. (The\nreason for the latter is so that uupdate can be called directly from uscan.)\n\nSince uupdate uses debuild to clean the current archive before trying to apply a patch file,\nit accepts a --rootcmd or -r option allowing the user to specify a gain-root command to be\nused. The default is to use fakeroot.\n\nIf an archive is being built, the pristine upstream source should be used to create the\n.orig.tar.gz file wherever possible. This means that MD5 sums or other similar methods can\nbe used to easily compare the upstream source to Debian's copy of the upstream version. This\nis the default behaviour, and can be switched off using the --no-pristine option below.\n", "subsections": [] }, "OPTIONS": { "content": "This is a summary of what was explained above.\n\n--no-conf, --noconf\nDo not read any configuration files.
