 `prefix` is a Tcl variable. If you need it outside of Tcl, for example in
 a source code file, you add a patchfile that puts a `@PREFIX@` placeholder
 into the file in the right place, and then you replace the placeholder
 with the variable's value like this:

 {{{
 post-patch {
     reinplace -W ${worksrcpath} "s|@PREFIX@|${prefix}|g" somefile.sh
 someotherfile.sh
 }
 }}}

 A lot of methods contain bashisms which are not portable (in particular to
 dash or zsh). The verlt-verle is the softest solution I could find, at the
 cost of depending on a sort -V implementation.

 As I said, the proposals are of varying portability. :) `sort -V` isn't
 portable.
