EMBASSY is a collection of contributed EMBOSS software. From the web
“EMBOSS is GPL licensed. The libraries are under the Lesser GPL (LGPL).
Programs which have been included from third parties who have their own
licencing terms are kept apart under the EMBASSY grouping.
This allows the EMBOSS libraries to link to other software, and only
requires that software to have an LGPL-compatible licence. Phylip, for
example, fits this model.
But, to the user they do look exactly like EMBOSS aplications.”
