18 The effect of --gnu and --gnits

The ‘--gnu’ option (or ‘gnu’ in the ‘AUTOMAKE_OPTIONS’ variable) causes automake to check the following:

• The files INSTALL, NEWS, README, COPYING, AUTHORS, and ChangeLog are required at the topmost directory of the package.
• The options ‘no-installman’ and ‘no-installinfo’ are prohibited.

Note that this option will be extended in the future to do even more checking; it is advisable to be familiar with the precise requirements of the GNU standards. Also, ‘--gnu’ can require certain non-standard GNU programs to exist for use by various maintainer-only targets; for instance in the future pathchk might be required for ‘make dist’.

The ‘--gnits’ option does everything that ‘--gnu’ does, and checks the following as well:

• ‘make dist’ will check to make sure the NEWS file has been updated to the current version.
• The file COPYING.LIB is prohibited. The LGPL is apparently considered a failed experiment.
• ‘VERSION’ is checked to make sure its format complies with Gnits standards.
• If ‘VERSION’ indicates that this is an alpha release, and the file README-alpha appears in the topmost directory of a package, then it is included in the distribution. This is done in ‘--gnits’ mode, and no other, because this mode is the only one where version number formats are constrained, and hence the only mode where automake can automatically determine whether README-alpha should be included.
• The file THANKS is required.
