| 25 | # checksums of each files. When the program starts up, this manifest file is
|

|
---|
| 27 | # updated and new files are downloaded with names that are created by appending
|
---|
| 28 | # the checksum to the actual name, so as not to overwrite any existing files at
|
---|
| 29 | # this stage. If all files are downloaded, the downloaded files are renamed to
|
---|
| 30 | # their real names. On Windows, the old file is removed first to avoid trouble
|
---|
| 31 | # with 'busy' files. If removing a file fails, the file will be moved to a
