libghc-hstringtemplate-dev 0.8.7-4 (arm64 binary) in ubuntu eoan

 This is a Haskell template engine. Its API is mainly inspired to that of
 the Java library StringTemplate, but it is implemented in a "Haskellish"
 manner.
 .
 It implements the basic 3.1 grammar, lacking group files (though not
 groups themselves), Regions, and Interfaces and extends it by allowing
 the application of alternating attributes to anonymous as well as
 regular templates, including therefore sets of alternating attributes.
 .
 This package provides a library for the Haskell programming language.
 See http://www.haskell.org/ for more information on Haskell.
