+## strip
+
+The option `-C strip=val` controls stripping of debuginfo and similar auxiliary
+data from binaries during linking.
+
+Supported values for this option are:
+
+- `none` - debuginfo and symbols (if they exist) are copied to the produced
+  binary or separate files depending on the target (e.g. `.pdb` files in case
+  of MSVC).
+- `debuginfo` - debuginfo sections and debuginfo symbols from the symbol table
+  section are stripped at link time and are not copied to the produced binary
+  or separate files.
+- `symbols` - same as `debuginfo`, but the rest of the symbol table section is
+  stripped as well if the linker supports it.
+
 ## target-cpu
 
 This instructs `rustc` to generate code specifically for a particular processor.
