Improve help text

[gabejohnson]

As a new psc-package user I struggled yesterday to perform the most basic of tasks, an initial package set install.

Neither the help text, nor the README provide any guidance in this regard. In fact, the README seems to target package authors with little thought to package users.

With some help I discovered psc-package update was what I needed, but that command and the associated help text Update dependencies have different semantics from an initial install.

I propose improving the help text for a few of the commands:

init Initialize a new package -> Create a new psc-package.json file update Update dependencies -> Install or update package dependencies build Build the current package and dependencies -> Update dependencies and compile the current package

Additionally, a line near the top of the README regarding initial install would be helpful. Something along the lines of:

# installs the project dependencies listed in psc-package.json
psc-package update

Another option is to have install with no package specified be an alias for update

I think this all seems reasonable. Any objections?

Sounds good
