# About Fossil

Fossil is a distributed version control system that has been widely
used since 2007.  Fossil was originally designed to support the
[SQLite](https://sqlite.org) project but has been adopted by many other
projects as well.

Fossil is self-hosting at <https://fossil-scm.org>.

If you are reading this on GitHub, then you are looking at a Git mirror
of the self-hosting Fossil repository.  The purpose of that mirror is to
test and exercise Fossil's ability to export a Git mirror.  Nobody much
uses the GitHub mirror, except to verify that the mirror logic works.  If
you want to know more about Fossil, visit the official self-hosting site
linked above.

README.autosetup created by autosetup v0.6.9

This is the autosetup directory for a local install of autosetup.
It contains autosetup, support files and loadable modules.

*.tcl files in this directory are optional modules which
can be loaded with the 'use' directive.

*.auto files in this directory are auto-loaded.

#
# A boolean option is of the form:
#
## name[=0|1]  => "Description of this boolean option"
#
# The default is 'name=0', meaning that the option is disabled by default.
# If 'name=1' is used to make the option enabled by default, the description should reflect
# that with text like "Disable support for ...".
#
# An argument option (one which takes a parameter) is of the form:
#
## name:[=]value  => "Description of this option"
#
# If the 'name:value' form is used, the value must be provided with the option (as '--name=myvalue').
# If the 'name:=value' form is used, the value is optional and the given value is used as the default
# if it is not provided.
#
# The description may contain '@default@', in which case it will be replaced with the default
# value for the option (taking into account defaults specified with 'options-defaults'.
#
# Undocumented options are also supported by omitting the '=> description'.
# These options are not displayed with '--help' and can be useful for internal options or as aliases.
#
# For example, '--disable-lfs' is an alias for '--disable=largefile':

# Configuration subroutine to validate and canonicalize a configuration type.

# 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.

#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
