+# rust2rpm
+
+Convert Rust crates to RPM.
+
+## `.rust2rpm.conf`
+
+You can place configuration file which is used as source for additional
+information for spec generation.
+
+Some simple example would be better than many words ;)
+
+```ini
+[DEFAULT]
+buildrequires =
+  pkgconfig(foo) >= 1.2.3
+lib.requires =
+  pkgconfig(foo) >= 1.2.3
+
+[fedora]
+bin.requires =
+  findutils
+buildrequires =
+lib.requires =
+lib+default.requires =
+  pkgconfig(bar) >= 2.0.0
