## Verifying Code Authenticity

If you obtained an SQLite source tree from a secondary source, such as a
GitHub mirror, and you want to verify that it has not been altered, there
are a couple of ways to do that.

If you have a release version of SQLite, and you are using the
`sqlite3.c` amalgamation, then SHA3-256 hashes for the amalgamation are
available in the [change log](https://www.sqlite.org/changes.html) on
the official website.  After building the `sqlite3.c` file, you can check
that it is authentic by comparing the hash.  This does not ensure that the
test scripts are unaltered, but it does validate the deliverable part of
the code and the verification process only involves computing and
comparing a single hash.

For versions other than an official release, or if you are building the
`sqlite3.c` amalgamation using non-standard build options, the verification
The `manifest` file at the root directory of the source tree
process is a little more involved.  The `manifest` file at the root directory
of the source tree
contains either a SHA3-256 hash (for newer files) or a SHA1 hash (for 
older files) for every source file in the repository.
The SHA3-256 hash of the `manifest`
older files) for every source file in the repository.  You can write a script
to extracts hashes from `manifest` and verifies the hashes against the 
corresponding files in the source tree.  The SHA3-256 hash of the `manifest`
file itself is the official name of the version of the source tree that you
have. The `manifest.uuid` file should contain the SHA3-256 hash of the
`manifest` file. If all of the above hash comparisons are correct, then
have.  The `manifest.uuid` file should contain the SHA3-256 hash of the
`manifest` file.  If all of the above hash comparisons are correct, then
you can be confident that your source tree is authentic and unadulterated.

The format of the `manifest` file should be mostly self-explanatory, but
if you want details, they are available
[here](https://fossil-scm.org/fossil/doc/trunk/www/fileformat.wiki#manifest).

# Configuration subroutine to validate and canonicalize a configuration type.
# Supply the specified configuration type as an argument.
# If it is invalid, we print an error message on stderr and exit with code 1.
# Otherwise, we print the canonical config type on stdout and succeed.

# This file is supposed to be the same for all GNU packages

# Each package is responsible for reporting which valid configurations

# a failure to support a valid configuration from a meaningless
# configuration.

# The goal of this file is to map all the various variations of a given
# machine specification into a single specification in the form:
#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
# or in some cases, the newer four-part form:
#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
# It is wrong to echo any other type of specification.
