HandyG.jl

Julia bindings for the Fortran library handyG (rapid numerical evaluation of generalized polylogarithms / GPLs).

This documentation focuses on:

• A Julia API that stays close to the upstream Fortran calling conventions
• Allocation-free hot paths (G, G!, G_batch!) after warmup
• Cross-platform binaries via HandyG_jll (BinaryBuilder/Yggdrasil)

Where to start
