Regarding php script licenses

[athos-ribeiro]

Hello,

While browsing through the code in this repository, I realized that the following files are licensed under PHP-3.0:

configure.php
scripts/file-entities.php.in
scripts/test_missing-entities.php.in
scripts/missing-entities.php.in
scripts/check-trans-params.php
scripts/docgen/docgen.php
scripts/spell-checker.php
scripts/genPHP_INI_ENTRY.php
scripts/xml-check.php
scripts/check-trans.php
scripts/qa/entity-usage.php
scripts/qa/section-order.php
scripts/qa/check-acronyms.php
scripts/qa/checkent.php
scripts/qa/entities.php
scripts/qa/extensions.xml.php
scripts/qa/check-valid-function.php
scripts/dbtags.php
scripts/process.php
scripts/check-trans-maint.php
scripts/versions.php
scripts/notes_stats.php
scripts/revcheck.php
scripts/include/FileData.class.php
scripts/include/lib-translations.inc.php
scripts/orphan_notes.php
scripts/notes_extract.php
scripts/check_phpdoc/view_check_phpdoc.php
scripts/check_phpdoc/build.php
scripts/aspell.php

Would it be possible to re-license those as PHP-3.01 to make it easier to re-distribute the documentation? What sort of effort would it take to do so (e.g., contacting authors, filing PRs, etc)?
