Gotcha is a library that wraps functions. Tools can use gotcha to install hooks into other libraries, for example putting a wrapper function around libc's malloc. It is similar to LD_PRELOAD, but operates via a programmable API. This enables easy methods of accomplishing tasks like code instrumentation or wholesale replacement of mechanisms in programs without disrupting their source code.

EasyBuild support

Version 1.0.8 for CPE 24.03
