//! Define storage persistent across different runs of a program
/*! This macro is used to mark initialized data (doesn't apply to
uninitialized data) as `persistent' data.
This data will be saved across different runs of the program.
Usage:
You should insert __persistent between the variable name and equal
sign followed by value, e.g:
static int counter __persistent = 0;
static char data[] __persistent = { 0x32, 0x36, ... };
