| 171 """Class to automatically find SVN tags and help package them | |
| 172 | |
| 173 The tags are found using three parameters: | |
| 174 url -- The base url of the SVN tags directory to use | |
| 175 pattern -- A regular expression matching the subdirectories to | |
| 176 consider in the tag directory specified by the url | |
| 177 subdir -- A subdirectory of the directory matched by pattern to | |
| 178 export and use to determine revision number | |
| 179 | |
| 180 The subdir parameter is there to cope with the kdepim enterprise | |
| 181 tags. The URL for a tag is of the form | |
| 182 .../tags/kdepim/enterprise4.0.<date>.<rev> . Each such tag has | |
| 183 subdirectories for kdepim, kdelibs, etc. The url and pattern are | |
| 184 used to match the URL for the tag, and the subdir is used to select | |
| 185 which part of the tag is meant. | |
| 186 | |
| 187 The subdir also determines which SVN directory's revision number is | |
| 188 used. Normally, just appending the subdir to the tag URL would be | |
| 189 enough for this, but the situation is more complex for | |
| 190 kdebase_workspace and kdebase_runtime, whose code comes from | |
| 191 different subdirectories of the kdebase-4.X-branch subdirectory (for | |
| 192 enterprise4 tags). Here the revision number must be taken from | |
| 193 kdebase-4.X-branch, but the URL to use when exporting the sources, | |
| 194 must refer to e.g. kdebase-4.1-branch/kdebase_workspace. To achieve | |
| 195 that, subdir may contain slashes to indicate subdirectories of | |
| 196 subdirectories, but only the first part of subdir (up to the first | |
| 197 slash) is used when determining the revision number. | |
