\&  pinto \-\-root=REPOSITORY_ROOT merge [OPTIONS] STACK [INTO_STACK]

.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
!! \s-1THIS COMMAND IS EXPERIMENTAL\s0 !!
.PP
This command joins the history of one stack with another.  At present, it is
only capable of doing a \*(L"fast-forward\*(R" merge when the head of \s-1STACK\s0 is a
direct descendant of the head of \s-1INTO_STACK.\s0
.SH "COMMAND ARGUMENTS"
.IX Header "COMMAND ARGUMENTS"
The first mandatory argument is the name of the stack to merge from.  The
second optional argument is the name of the stack to merge to.  If the second
argument is not specified, it defaults to whichever stack is currently marked
as the default.  Here are some examples:
.PP
.Vb 2
\&  pinto ... merge dev               # Merge the "dev" stack into the default stack
\&  pinto ... merge dev prod          # Merge the "dev" stack into the "prod" stack
.Ve
.SH "COMMAND OPTIONS"
.IX Header "COMMAND OPTIONS"
.IP "\-\-dry\-run" 4
.IX Item "--dry-run"
Go through all the motions, but do not actually commit any changes to the
repository.  At the conclusion, a diff showing the changes that would have
been made will be displayed.  Use this option to see how upgrades would
potentially impact the stack.
.IP "\-\-message=TEXT" 4
.IX Item "--message=TEXT"
.PD 0
.IP "\-m \s-1TEXT\s0" 4
.IX Item "-m TEXT"
.PD
Use \s-1TEXT\s0 as the revision history log message.  If you do not use the
\&\f(CW\*(C`\-\-message\*(C'\fR option or the \f(CW\*(C`\-\-use\-default\-message\*(C'\fR option, then you will be
prompted to enter the message via your text editor.  Use the \f(CW\*(C`PINTO_EDITOR\*(C'\fR
or \f(CW\*(C`EDITOR\*(C'\fR or \f(CW\*(C`VISUAL\*(C'\fR environment variables to control which editor is
used.  A log message is not required whenever the \f(CW\*(C`\-\-dry\-run\*(C'\fR option is set,
or if the action did not yield any changes to the repository.
.IP "\-\-use\-default\-message" 4
.IX Item "--use-default-message"
.PD 0
.IP "\-M" 4
.IX Item "-M"
.PD
Use the default value for the revision history log message.  Pinto will
generate a semi-informative log message just based on the command and its
arguments.  If you set an explicit message with \f(CW\*(C`\-\-message\*(C'\fR, the \f(CW\*(C`\-\-use\-
default\-message\*(C'\fR option will be silently ignored.
