+# GDB Common Version 1.
+#
+# This configuration file configure's, make's and install's gdb.
+#
+
+#
+# Python
+#
+# GDB uses python internally so we need to link to a suitable python
+# dev kit. The dev kit for python is the header and a library. These
+# files are versioned where the header file is located in a directory
+# based on:
+#
+#  pythonM.m/Python.h
+#
+# where 'M' is the major version number and 'm' is the minor verison
+# number. The library is:
+#
+#  libpythonM.m.a
+#
+# The python command is 'pythonM' which means we need to query it for
+# the minor number.
+#
+# The python running the RSB may not be suitable, for example a MSC,
+# MSYS or Cygwin version on Windows when we want the MinGW python dev
+# file. A specific version cannot be forced because older versions of
+# GDB can only link to 'python2'.
+#
+# Host support can perform a complex query of the system, for example
+# Windows and set '%{gdb_python2}' and '%{gdb_python3}' with the full
+# path to that version's executable.
+#
+# A configuration of GDB can set the version required by setting
+# '%{gdb-python-version}' to the versions command, eg python2.
+#
+# The procedure is:
+#
+# 1. If the macros '%{gdb_python2}' or '%{gdb_python3}' are present
+#    use that path they contain. Assume the path is valid.
+#
+# 2. Does the version of gdb specify a version of python that must be
+#    used. Override with '%define gdb-python-version python2'.
+#
+# 3. Search for 'python2' and if not found search for 'python3'.
