PHP distribution generator

Creates PHP release packages (tar.gz, tar.bz2, tar.xz) from the php-src Git
repository. The snapshot archive includes also generated configure script,
configuration headers, parsers, lexers, and similar generated files to simplify
the installation on the *nix systems.

SYNOPSIS:
  makedist [options] <tree-ish>

OPTIONS:
  -h, --help        Display this help.
  --remote=<repo>   Instead of using a local repository, retrieve a tar archive
                    from a remote repository.
  <tree-ish>        The Git tree or Git commit to produce an archive for. This
                    script needs a consistent tagging of releases. Each release
                    of a package should have a tag of the form:
                      php-X.Y.Z[alpha|beta|RC]

                    or branch:
                       PHP-X.Y[.Z]

                    Where:
                      - X is major version number
                      - Y is minor version number
                      - Z is patch version number
                      - last part of tag is optional and is one of RC, alpha, or
                        beta and belonging number.

EXAMPLES:

  Create snapshot of the master branch:
    scripts/dev/makedist

  Create snapshot of the PHP-7.4 branch:
    scripts/dev/makedist PHP-7.4

  Create release packages for the stable tag php-7.4.0:
    scripts/dev/makedist php-7.4.0

  Create release candidate packages for the tag php-7.4.0RC1:
    scripts/dev/makedist php-7.4.0RC1

  Create release packages from a remote Git repository for the tag php-7.4.0:
    scripts/dev/makedist --remote=git@git.php.net:php-src.git php-7.4.0
