+?X:
+?X: When running Configure remotely ($src is not '.'), we cannot source
+?X: the files directly, since that would wrongly cause the extraction
+?X: where the source lie instead of withing the current directory. Therefore,
+?X: we need to 'sh <file' then, which is okay since they will source the
+?X: existing config.sh file. It's not possible to use:
+?X: ../src/Configure -S -O -Dsomething
+?X: unfortunately since no new config.sh with the -Dsomething override
+?X: will be created before running the .SH files. A minor buglet.
+?X:
+?X: Note that we must create the directory hierarchy ourselves if it does
+?X: not exist already, and that is done through a shell emulation of the
+?X: 'mkdir -p' command. We don't want to use the $installdir metaconfig
+?X: symbol here since that would require too much to be configured for
+?X: this simple extraction task that may happen quickly with 'Configure -S'.
