/*
* ------------------------------
* Compile time directives
* ------------------------------
* For most purposes, PH7 can be built just fine using the default compilation options.
* However, if required, the compile-time options documented below can be used to omit
* PH7 features (resulting in a smaller compiled library size) or to change the default
* values of some parameters.
* Every effort has been made to ensure that the various combinations of compilation
* options work harmoniously and produce a working library.
*
* Options To Omit/Enable Features:
* The following options can be used to reduce the size of the compiled library
* by omitting optional features. This is probably only useful in embedded systems
* where space is especially tight, as even with all features included the PH7 library
* is relatively small. Don't forget to tell your compiler to optimize for binary
* size! (the -Os option if using GCC).
* Telling your compiler to optimize for size usually has a much larger impact
* on library footprint than employing any of these compile-time options.
* PH7_DISABLE_DISK_IO
* If this directive is enabled, built-in Virtual File System functions such as
* chdir(), mkdir(), chroot(), unlink(), delete(), etc. are omitted from the build.
