A PoC environment manager for J. Currently a single script that will only run on Linux. Idea is to have a single management point on the user's computer, to manage the various J versions, and projects.
Management files are put into the $HOME/.jman directory.
Create a new project, called myproject, using J 701
./installer.sh myproject 701
If J701 is not installed, the script will download the files and install,
before creating the project folder.
