23:15 | Slight fix to 'after' cleanup handling. check-in: 7960da64e8 user: mistachkin tags: trunk | |
22:39 | Add header comments to all procedures. Make sure to cleanup any 'after' events created when downloading via HTTP in native Tcl. Add language and version argument validation to the 'downloadFiles' procedure. check-in: 3cdc48fb08 user: mistachkin tags: trunk | |
20:06 | Rename the package 'IfNeeded' piece of metadata to simply 'Script', since it may or may not actually be a real 'package ifneeded' script. check-in: b868c01046 user: mistachkin tags: trunk | |
