_________________ The iftex package v0.2 This very simple package, for both Plain TeX and LaTeX, defines the \ifPDFTeX, \ifXeTeX, and \ifLuaTeX boolean for testing whether PDFTeX, or XeTeX, or LuaTeX is being used for typesetting. Also provides the \RequirePDFTeX, \RequireXeTeX, and \RequireLuaTeX command which throws an error if PDFTeX, XeTeX and LuaTeX (respectively) is not the engine in use. If you want to report any bugs or typos and corrections in the documentation, or ask for any new features, or suggest any improvements, or ask any questions about the package, then please do not send any direct emails to us; we will not answer any direct emails. Instead please use the issue tracker: <https://github.com/persian-tex/iftex/issues> In doing so, please always explain your issue well enough, always include a minimal working examples showing the issue, and always choose the appropriate label for your query (i.e. if you are reporting any bugs, choose `bug' label).
