Configuring the Garbage Collector

[cam-bam]

What effect does the disable:1 option have on garbage collection? 
Does it stop garbage collection entirely or just prevent them 
from running at the start of the program? From this 
[link](https://dlang.org/spec/garbage.html#gc_config) I can see 
there are multiple options however, if I wanted to avoid the 
garbage collector entirely would it be best to just use betterC 
or do manual memory management as suggested by the 
[blog](https://dlang.org/blog/2017/09/25/go-your-own-way-part-two-the-heap/) here which mentions using the c std. library.
