The sdmTMB package includes other open source software components. The following
is a list of these components.

The following are licensed under GPL-3 as included for sdmTMB:
1. VAST for the general structure of the original TMB model code
(heavily modified into src/sdmTMB.cpp), anisotropy plotting code (modified
into R/plot.R plot_anisotropy() and plot_anisotropy2()), approach to
bias correction (R/index.R get_generic()), and approach to optimization
(modified into R/extra-optimization.R)
The following are licensed under AGPL-3:
1. glmmTMB for general approach to prediction (heavily modified into
R/predict.R) selected parameterizations of the likelihood densities
(src/sdmTMB.cpp 'family' section: truncated distributions, nbinom1, Beta)
effects methods (R/methods.R Effect.sdmTMB()), and emmeans methods (emmeans.R).
The following are licensed under GPL-2:
1. SPDE barrier implementation (src/utils.h spde_barrier_t and R/mesh.R
make_barrier_spde())
2. Function to aid prediction from smooths from mgcv documentation
smooth2random() (R/smoothers.R s2rPred())
3. brms code snippets used to construct penalized smoother matrices with mgcv
tools (modified into R/smoothers.R parse_smoothers())
4. TMB anisotropy R implementation from TMB examples folder (R/mesh.R
make_anisotropy_spde()) and corresponding code in src/sdmTMB.cpp
