Usage: nix-instantiate [OPTIONS...] [FILES...]

`nix-instantiate' turns Nix expressions into store derivations. 

The argument `-' may be specified to read a Nix expression from
standard input.

Options:

  --version: output version information
  --help: display help

  --verbose / -v: verbose operation (may be repeated)

  --eval-only: evaluate and print resulting term; do not instantiate
  --parse-only: parse and print abstract syntax tree

  --attr / -A PATH: select an attribute from the top-level expression

  --add-root: add garbage collector roots for the result

For --eval-only / --parse-only:

  --xml: print an XML representation of the abstract syntax tree
  --no-location: don't provide source location information in the
    output XML tree

For --eval-only:

  --strict: compute attributes and list elements, rather than being
    lazy
