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!

31 ?T:PERL_CONFIG_SH dir file name create mkdir_p
32 ?LINT:use PERL_CONFIG_SH
33 : script used to extract .SH files with variable substitutions
36 echo "Doing variable substitutions on .SH files..."
37 if test -f MANIFEST; then
38 set x `awk '{print $1}' < MANIFEST | grep '\.SH$'`
40 echo "(Looking for .SH files under the source directory.)"
41 set x `(cd "$src"; find . -name "*.SH" -print)`
45 0) set x `(cd "$src"; echo *.SH)`; shift;;

50 ?X: script to emulate mkdir -p
55 if test ! -d "$name"; then
56 create="$name $create";
57 name=`echo $name | sed -e "s|^[^/]*$||"`;
58 name=`echo $name | sed -e "s|\(.*\)/.*|\1|"`;
63 for file in $create; do
72 dir=`expr X$file : 'X\(.*\)/'`
73 file=`expr X$file : 'X.*/\(.*\)'`
74 (cd "$dir" && . ./$file)
83 ?X: When running Configure remotely ($src is not '.'), we cannot source
84 ?X: the files directly, since that would wrongly cause the extraction
85 ?X: where the source lie instead of withing the current directory. Therefore,
86 ?X: we need to 'sh <file' then, which is okay since they will source the
87 ?X: existing config.sh file. It's not possible to use:
88 ?X: ../src/Configure -S -O -Dsomething
89 ?X: unfortunately since no new config.sh with the -Dsomething override
90 ?X: will be created before running the .SH files. A minor buglet.
92 ?X: Note that we must create the directory hierarchy ourselves if it does
93 ?X: not exist already, and that is done through a shell emulation of the
94 ?X: 'mkdir -p' command. We don't want to use the $installdir metaconfig
95 ?X: symbol here since that would require too much to be configured for
96 ?X: this simple extraction task that may happen quickly with 'Configure -S'.

115 : oops, they left it out of MANIFEST, probably, so do it anyway.
