A system of \fIpre\-run\fR, , etc is suggested; other options would be \fIpre\-run\-10\fR or \. A dot after the hook name is optional\. +. +.P +If you want to create hooks for a specific \fIvcsh\fR repository, simply prepend the repository\'s name, followed by a dot, i\.e\. \.

For example, adding a \fBsudo\fR(8) rule for \fBvcsh\fR would be pretty stupid\. +. +.P +Additionally, vcsh will source, i\.e\. execute, all files listed in \fICONFIG\fR\.
