+try_patches.sh
+~~~~~~~~~~~~~~
+This script gets three arguments (component (like binutils, gcc, glibc, ports),
+the directory containing sources to be patched and a directory containing
+patches). All patches (in the patches directory) are expected to follow this
+filename convention:
+
+	${3}/COMPONENT-nnn-some_description.patch
+

--- NEW FILE: try_patches.sh ---
#!/bin/sh

#
# $1 - component to patch (gcc, glibc, ports, binutils)
# $2 - destination directory; patches are expected to apply with -p1
# $3 - directory containing the patches
#
