This is an include file that simply imports common modules for your convenience.
Example:
import std/prelude include std/prelude # same as: # import std/[os, strutils, times, parseutils, hashes, tables, sets, sequtils, parseopt, strformat] let x = 1 assert "foo $# $#" % [$x, "bar"] == "foo 1 bar" assert toSeq(1..3) == @[1, 2, 3] when not defined(js) or defined(nodejs): assert getCurrentDir().len > 0 assert ($now()).startsWith "20"
