    99Sets memory allocator. 
    1010 
    11 Currently, we have only one choice:  the memory allocator in 
    12 F<src/gc/alloc_resources.c>. 
    13  
    14 In the future, we will have a C<--gc> command-line option which will enable 
    15 the configurer to choose among several garbage collectors. 
     11The C<--gc> command-line option enables the configurer to choose among 
     12several garbage collectors.  Current available options are: 
    1613 
    1714=over 4 
    1815 
     16=item ms 
     17 
     18Stop-the-world mark & sweep 
     19 
     20=item inf 
     21 
     22Infinite memory "collector" 
     23 
     24=item ms2 
     25 
     26New style mark & sweep 
     27 
     28=item gms 
     29 
     30Generational M&S based on MS2 
     31 
    1932=back 
    2033 
     34The choice is stored as C<gc_type> in C<%PConfig>, and available 
     35(uppercased) as PARROT_GC_DEFAULT_TYPE in F<parrot/config.h> 
     36 
     37For backwards compatibility with parrot 3.1.0 and earlier, an empty 
     38entry C<gc_flag> is maintained.  (It used to be used in Makefiles to 
     39append to the C compiler flags.)
