+SYNTAX CHECKERS FOR JULIA                           *syntastic-checkers-julia*

+The following checkers are available for Julia (filetype "julia"):
+
+    1. lint.....................|syntastic-julia-lint|
+
+------------------------------------------------------------------------------
+1. lint                                                 *syntastic-julia-lint*
+
+Name:        lint
+Maintainer:  LCD 47 <lcd047@gmail.com>
+
+This is a checker for Julia files (https://julialang.org/), using the Julia
+package "Lint". See the package's documentation for more information:
+
+    http://lintjl.readthedocs.io/
+
+Installation~
+
+You need to install Julia itself, and the package "Lint". You can install
+"Lint" from the Julia package manager, with the command: >
+    Pkg.add("Lint")
+
+Checker Options~
+
+This checker doesn't call the "makeprgBuild()" function, and thus it ignores
+the usual 'g:syntastic_julia_lint_<option>' variables. The only exception is
+'g:syntastic_julia_lint_exec', which can still be used to override the "julia"
+executable.
