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! | |

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