 +===== Build MariaDB with readline support ===== 
 + 
 +I've been frustrated with the use of editline (libedit) instead of readline that MariaDB is now built with in Debian 11. I have found editline to be buggy: its implementation of Ctrl-R and editing of wrapped lines do not work wellplus Ctrl-W not being mapping to delete a word by default is infuriating! 
 + 
 +As I understand it, Debian is no longer able to distribute MariaDB built against readline as the former is GPL2 and the latter GPL3, and apparently the 2 are incompatible for distribution. So I have written instructions ​for [[how to rebuild MariaDB against readline in Debian]].
