Hi all,

The attached patch implements an option that allows loading \backslash
macros from a user-defined file.

A macro file is defined as a two-column text file which maps macro names
to their values. Any whitespace is interpreted as a column delimiter. An
example is attached alongside the patch.

Cheers,
