22 ?X: This unit produces a shell script which can be doted in order to extract
23 ?X: .SH files with variable substitutions.
25 ?X: When running Configure from a remote directory ($src is not '.'),
26 ?X: then the files will be created in that directory, so beware!

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