## @arr[in] precmd_functions
4+
## @arr[in] preexec_functions
5+
## The functions registered to these arrays are executed on PRECMD and
6+
## PREEXEC hooks, respectively.
7+
##
8+
## @fn[in] precmd
9+
## @fn[in] preexec
10+
## If these functions are defined, they are executed on PRECMD and PREEXEC
11+
## hooks, respectively, through "precmd_functions" and "preexec_functions".

##
13+
##
14+
## * Integration with bash-preexec.sh (https://github.com/rcaloras/bash-preexec)
15+
##
16+
## Although this script works without bash-preexec, it provides a better
17+
## integration with bash-preexec when bash-preexec is loaded. The
18+
## integration relies on the following public API of bash-preexec.
