  17 # Compilation environments.
  18 #
  19 # Each compilation environment is declared using the keyword "env", like
  20 # this:
  21 #
  22 # env | <name> | <std> | <defs>
  23 #
  24 # <name> is just a symbolic name for environment.
  25 # <std>  indicates either c89 or c99, i.e. which C standard to compile
  26 #        under.  This infuences choice of compiler and switches.
  27 # <defs> is a list of CPP style -D or -U flags to define C preprocessor
  28 #        symbols.
  29 #
  30 # Groups of compilation environments can be named, using the "env_group"
  31 # keyword (this can also be used to create aliases):
  32 #
  33 # env_group | <name> | <envs>
  34 #
  35 # <name> is a name for the group or alias
  36 # <envs> is a whitespace separated list of previously declared environments
  37 #        or environment groups (or aliases).
