+# A simple utility script for neomutt to use your favorite cli
+# file manager to work with files in neomutt.
+# Can add attachments to emails or save attachments in a chosen directory.
+#
+# Use it as `neomutt-filer attach <my-base-dir>`
+# or `neomutt-filer saveto <my-base-dir>`
+#
+# Can be bound to neomutt macros like the following:
+#
+# macro compose A '<enter-command>source "neomutt-filer attach"|<enter>' "Attach with file manager"
+# macro attach S '<enter-command>source "neomutt-filer saveto"|<enter>' "Save attachment to dir"
