NAME
dh_testversion − ensure that the correct version of debhelper is installed
SYNOPSIS
dh_testversion [debhelper options] [operator] [version]
DESCRIPTION
Note: This program is deprecated. You should use build dependencies instead.
dh_testversion compares the version of debhelper against the version you specify, and if the condition is not met, exits with an error message.
You can use this in your debian/rules files if a new debhelper feature is introduced, and your package requires that feature to build correctly. Use debhelper’s changelog to figure out the version you need.
Be sure not to overuse dh_testversion. If debhelper version 9.5 introduces a new dh_autofixbugs command, and your package uses it, then if someone tries to build it with debhelper 1.0, the build will fail anyway when dh_autofixbugs cannot be found, so there is no need for you to use dh_testversion.
OPTIONS
operator
Optional comparison operator used in comparing the versions. If not specified, ">=" is used. For descriptions of the comparison operators, see dpkg −−help.
version
Version number to compare against the current version of debhelper. If not specified, dh_testversion does nothing.
SEE ALSO
This program is a part of debhelper.
