| 21 """Class to automatically find SVN tags and help package them | |
| 22 | |
| 23 The tags are found using three parameters: | |
| 24 url -- The base url of the SVN tags directory to use | |
| 25 pattern -- A regular expression matching the subdirectories to | |
| 26 consider in the tag directory specified by the url | |
| 27 subdir -- A subdirectory of the directory matched by pattern to | |
| 28 export and use to determine revision number | |
| 29 | |
| 30 The subdir parameter is there to cope with the kdepim enterprise | |
| 31 tags. The URL for a tag is of the form | |
| 32 .../tags/kdepim/enterprise4.0.<date>.<rev> . Each such tag has | |
| 33 subdirectories for kdepim, kdelibs, etc. The url and pattern are | |
| 34 used to match the URL for the tag, and the subdir is used to select | |
| 35 which part of the tag is meant. | |
| 36 | |
| 37 The subdir also determines which SVN directory's revision number is | |
| 38 used. Normally, just appending the subdir to the tag URL would be | |
| 39 enough for this, but the situation is more complex for | |
| 40 kdebase_workspace and kdebase_runtime, whose code comes from | |
| 41 different subdirectories of the kdebase-4.X-branch subdirectory (for | |
| 42 enterprise4 tags). Here the revision number must be taken from | |
| 43 kdebase-4.X-branch, but the URL to use when exporting the sources, | |
| 44 must refer to e.g. kdebase-4.1-branch/kdebase_workspace. To achieve | |
| 45 that, subdir may contain slashes to indicate subdirectories of | |
| 46 subdirectories, but only the first part of subdir (up to the first | |
| 47 slash) is used when determining the revision number. | |
