# SYNOPSIS
#
#   Cosmopolitan C Runtime.
#
# OVERVIEW
#
#   This is a special object library defining the Cosmopolitan SysV
#   userspace runtime entrypoint, i.e. _start(). The $(CRT) argument
#   should come first in the link order when building ELF binaries;
#   becauseo it's the lowest level function; it wraps main(); and it
#   decides which runtime support libraries get schlepped into builds.
#
#   Please note that, when building an Î±cÏÂµÎ±lly pÎ´rÏÎ±blÎµ ÎµxÎµcÂµÏÎ±blÎµ,
#   lower-level entrypoints exist and as such, $(CRT) will generally
#   come second in link-order after $(APE).
