 An example of template file:

+  set -eo pipefail
   cd /myapp
   {{INSTALL}}
   ## Now we can assume there are |perl| and |local/bin/pmbp.pl|.
   perl local/bin/pmbp.pl --install-commands "make git"
   git clone https://url/of/component
   cd component && make deps
 
+This would install an application into C</myapp>.

+Another example template file:

+  #!/bin/bash
+  set -eo pipefail

+  cd $rootpath
+  {{INSTALL}}
+  perl local/bin/pmbp.pl --install-make && \
+  make deps && \

+The generated script is expected to be placed in the application
+source tree's root directory.  It would install the dependencies and
+then start the C<bin/local-server> program.
