The location of
.zshrcis not always$HOME/.zshrc. The environment variableZDOTDIRdefines in which directory.zshrcis in. Thus this contribution uses parameter expansion to check ifZDOTDIRis set and in that case uses that directory to locate.zshrc. IfZDOTDIRis not set,$HOMEis used as fallback directory.
