#452: Improve --help. Add info about installing specific versions and the use of
predicates

Reporter: guest | Owner:

Component: Cabal library | Version: 1.2.3.0
Severity: normal | Keywords:

----------------------------+-----------------------------------------------
It is possible to install a specific version of a package with the
following syntax.
cabal install <package>-<version>
e.g. cabal install haskell-src-exts-0.4.3.1
However, no mention is made of this in the --help.
Also, it is possible to use predicates. e.g. cabal install haskell-src-
exts<=0.4 to install a particular version of a package.
This should also be mentioned in the --help (along with a helpful remind
to quote the ">" character with "\>" if you don't want to redirect your
output in most shells!
