-%description
-dwarves is a set of tools that use the debugging information inserted in
-ELF binaries by compilers such as GCC, used by well known debuggers such as
-GDB, and more recent ones such as systemtap.
-
-Utilities in the dwarves suite include pahole, that can be used to find
-alignment holes in structs and classes in languages such as C, C++, but not
-limited to these.
-
-It also extracts other information such as CPU cacheline alignment, helping
-pack those structures to achieve more cache hits.
-
-These tools can also be used to encode and read the BTF type information format
-used with the Linux kernel bpf syscall, using 'pahole -J' and 'pahole -F btf'.
-
-A diff like tool, codiff can be used to compare the effects changes in source
-code generate on the resulting binaries.
-
-Another tool is pfunct, that can be used to find all sorts of information about
-functions, inlines, decisions made by the compiler about inlining, etc.
-
-One example of pfunct usage is in the fullcircle tool, a shell that drivers
-pfunct to generate compileable code out of a .o file and then build it using
-gcc, with the same compiler flags, and then use codiff to make sure the
-original .o file and the new one generated from debug info produces the same
-debug info.
-
-Pahole also can be used to use all this type information to pretty print raw data
-according to command line directions.
-
-Headers can have its data format described from debugging info and offsets from
-it can be used to further format a number of records.
-
-The btfdiff utility compares the output of pahole from BTF and DWARF to make
-sure they produce the same results.

+%description
+dwarves is a set of tools that use the debugging information inserted in
+ELF binaries by compilers such as GCC, used by well known debuggers such as
+GDB, and more recent ones such as systemtap.
+
+Utilities in the dwarves suite include pahole, that can be used to find
+alignment holes in structs and classes in languages such as C, C++, but not
+limited to these.
+
+It also extracts other information such as CPU cacheline alignment, helping
+pack those structures to achieve more cache hits.
+
+These tools can also be used to encode and read the BTF type information format
+used with the Linux kernel bpf syscall, using 'pahole -J' and 'pahole -F btf'.
+
+A diff like tool, codiff can be used to compare the effects changes in source
+code generate on the resulting binaries.
+
+Another tool is pfunct, that can be used to find all sorts of information about
+functions, inlines, decisions made by the compiler about inlining, etc.
+
+One example of pfunct usage is in the fullcircle tool, a shell that drivers
+pfunct to generate compileable code out of a .o file and then build it using
+gcc, with the same compiler flags, and then use codiff to make sure the
+original .o file and the new one generated from debug info produces the same
+debug info.
+
+Pahole also can be used to use all this type information to pretty print raw data
+according to command line directions.
+
+Headers can have its data format described from debugging info and offsets from
+it can be used to further format a number of records.
+
+The btfdiff utility compares the output of pahole from BTF and DWARF to make
+sure they produce the same results.
