Take a look at the example file

Adrian Mariano sent an update of the documentation yesterday which
probably will be included in 1.1.50. Anyway, here's the section on
repeats:
--------------------------
In order to specify repeats, use the code(\repeat) keyword. By
default, repeats are printed with repeat symbols.
mudela(fragment,verbatim,center)(
c'1
\repeat semi 2 { c'4 d' e' f' }
\repeat semi 2 { f' e' d' c' })
In order to specify alternate endings, use the code(\alternative)
keyword.
mudela(fragment,verbatim,center)(
c'1
\repeat semi 2 {c'4 d' e' f'}
\alternative { {d'2 d'} {f' f} })
The code(semi) specifies that normal repeats will be printed. If
code(fold) is used instead then the alternatives will be stacked:
mudela(fragment,verbatim,center)(
c'1
\repeat fold 2 {c'4 d' e' f'}
\alternative { {d'2 d'} {f' f} })
When the repeats involve partial measures, it will be necessary to use
code(\partial) keywords in a somewhat unexpected way
to indicate some measure lengths.
mudela(fragment,verbatim)(
\context Staff { \relative c'{
\repeat semi 2 { \partial 4; e | c2 d2 | e2 f2 | }
\alternative { { g4 g g } {\partial 1; a a a a | b1 } }
}})
Repeats can be unfolded by setting the property Staff.unfoldRepeats.
