---
--- 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`.
