+copyright\_header.py
+====================
+
+Provides utilities for managing copyright headers of `The Bitcoin Core
+developers` in repository source files. It has three subcommands:
+
+```
+$ ./copyright_header.py report <base_directory> [verbose]
+$ ./copyright_header.py update <base_directory>
+$ ./copyright_header.py insert <file>
+```
+Running these subcommands without arguments displays a usage string.
+
+copyright\_header.py report \<base\_directory\> [verbose]
+---------------------------------------------------------
+
+Produces a report of all copyright header notices found inside the source files
+of a repository. Useful to quickly visualize the state of the headers.
+Specifying `verbose` will list the full filenames of files of each category.

+copyright\_header.py update \<base\_directory\> [verbose]
+---------------------------------------------------------
+Updates all the copyright headers of `The Bitcoin Core developers` which were
+changed in a year more recent than is listed. For example:
+```
+// Copyright (c) <firstYear>-<lastYear> The Bitcoin Core developers
+```
+will be updated to:
+```
+// Copyright (c) <firstYear>-<lastModifiedYear> The Bitcoin Core developers
+```
+where `<lastModifiedYear>` is obtained from the `git log` history.
+
+This subcommand also handles copyright headers that have only a single year. In
+those cases:
+```
+// Copyright (c) <year> The Bitcoin Core developers
+```
+will be updated to:
+```
+// Copyright (c) <year>-<lastModifiedYear> The Bitcoin Core developers
+```
+where the update is appropriate.
+
+copyright\_header.py insert \<file\>
+------------------------------------
+Inserts a copyright header for `The Bitcoin Core developers` at the top of the
+file in either Python or C++ style as determined by the file extension. If the
+file is a Python file and it has  `#!` starting the first line, the header is
+inserted in the line below it.
+
+The copyright dates will be set to be `<year_introduced>-<current_year>` where
+`<year_introduced>` is according to the `git log` history. If
+`<year_introduced>` is equal to `<current_year>`, it will be set as a single
+year rather than two hyphenated years.
+
+If the file already has a copyright for `The Bitcoin Core developers`, the
+script will exit.

-    tree-object-size: Deterministic SSA generation [PR123351]
-    
-    The order of evaluation of function arguments is unspecified in C++.
-    The function object_sizes_set_temp called object_sizes_set with two
-    calls to make_ssa_name() as arguments.  Since make_ssa_name() has the
-    side effect of incrementing the global SSA version counter, different
-    architectures of the same compiler evaluated these calls in different
-    orders.
-    
-    This resulted in non-deterministic SSA version numbering between
-    x86_64 and aarch64 hosts during cross-compilation, leading to
-    divergent object files.
-    
-    Sequencing the calls into separate statements ensures deterministic
-    evaluation order.

-    riscv: Fix incorrect jal with HIDDEN_JUMPTARGET
-    
-    A non-local STV_DEFAULT defined symbol is by default preemptible in a
-    shared object. j/jal cannot target a preemptible symbol. On other
-    architectures, such a jump instruction either causes PLT [BZ #18822], or
-    if short-ranged, sometimes rejected by the linker (but not by GNU ld's
-    riscv port [ld PR/28509]).
-    
-    Use HIDDEN_JUMPTARGET to target a non-preemptible symbol instead.
-    
-    With this patch, ld.so and libc.so can be linked with LLD if source
-    files are compiled/assembled with -mno-relax/-Wa,-mno-relax.
