+--- https://github.com/latex-lsp/texlab
+---
+--- A completion engine built from scratch for (La)TeX.
+---
+--- See https://github.com/latex-lsp/texlab/wiki/Configuration for configuration options.
+---
+--- There are some non standard commands supported, namely:
+--- `LspTexlabBuild`, `LspTexlabForward`, `LspTexlabCancelBuild`,
+--- `LspTexlabDependencyGraph`, `LspTexlabCleanArtifacts`,
+--- `LspTexlabCleanAuxiliary`, `LspTexlabFindEnvironments`,
+--- and `LspTexlabChangeEnvironment`.
