InspIRCd v4 is still early in development!
If you use this branch you may experience crashes, weird behaviour, and unannounced breaking changes.
You probably want to use InspIRCd v3 instead.
The "regex_posix" Module (v4)
This module depends on a UNIX-specific system library and must be manually enabled at compile time.
If you are running on a UNIX system you can enable this module using the following command:
./configure --enable-extras regex_posixDescription
This module provides the posix regular expression engine which uses the POSIX.2 regular expression matching system.
Configuration
To load this module use the following <module> tag:
<module name="regex_posix">
This module requires no other configuration.
