# This script creates the file `otherMakefiles.am` for the P4C compiler toolchain.
# The file is created by inserting "include" statements for other Makefile.am files.
# The included Makefile.am files are sought in two places:
# - all Makefile.am files found in the subdirectories of the "backends" directory.
#   These files are part of the "standard" back-ends distributed with the compiler.
# - all Makefile.am files found in subdirectories of the "extensions" directory.
#   These makefiles are part of customized extensions fo the compiler.
#   (The files in the "extensions" directory are not part of the compiler source tree;
#   they are expected to be symlinks to custom back-ends.)
