8This contains the following patch files in mailbox format.
9
10* 0001-Expose-line-and-column-information-for-use-in-PHP.patch
11  A PHP specific patch to expose the line and column number to PHP.
12* 0002-Track-implied-added-nodes-for-options-use-in-PHP.patch
13  A PHP specific patch to track implied added nodes for options.
14* 0003-Patch-utilities-and-data-structure-to-be-able-to-gen.patch
15  A PHP specific patch to patch utilities and data structure to be able to generate smaller lookup tables.
16  This patch won't be upstreamed because it breaks generality of those data structures, i.e. it only works
17  because we only use it for character encoding.
18* 0004-Remove-unused-upper-case-tag-static-data.patch
19  A PHP specific patch to remove unused upper case tag static data. This shrinks the static data size.
20* 0005-Shrink-size-of-static-binary-search-tree.patch
21  A PHP specific patch to shrink the size of the static binary search tree for entities.
22  This shrinks the static data size and reduces data cache pressure.
23* 0006-Patch-out-unused-CSS-style-code.patch
24  A PHP specific patch to remove CSS style and selector bindings from the Lexbor document.
25
26  **Note** for this patch the utilities to generate the tables are also patched.
27  Make sure to apply on a fresh Lexbor clone and run (in `lexbor/utils/encoding`): `python3 single-byte.py` and `python3 multi-byte.py` to generate the tables.
28  Also run `python3 tokenizer_entities_bst.py` to generate the static binary search tree for entities.
