  *  - com.woltlab.wcf is excluded from the next minor version on (`<excludedpackage version="6.3.0 Alpha 1">` for a
  *    minversion of 6.2.x), the package is not installable on a version it was not tested with
  *  - the delete PIPs (fileDelete.xml, templateDelete.xml, acpTemplateDelete.xml) run in every update
+ *  - the bootstrap file is named exactly like the package, character by character: the core only loads
+ *    lib/bootstrap/<package>.php (RebuildBootstrapper), on a case-sensitive file system a different casing is never loaded
+ *  - fileDelete runs before the files of an update when it deletes an old casing of the bootstrap file: on a
+ *    case-insensitive file system the extracted file keeps the old name and would be deleted afterwards
  *  - constants.php matches option.xml (written by apply.php; `--fix` writes it here)
  *
  * Usage: php tests/lint/check-package.php [--fix]
