+%%%%%%%% PSEUDOINDENT FUNCTIONS %%%%%%%%
+
+% these two functions are for indenting individual systems
+% - to left-indent a system, apply \pseudoIndent before the music continues
+% - \pseudoIndents is similar, but lets you also indent on the right
+% - both provide an option for changing that system's instrument names
+
+% N.B. these functions
+% - assume application to non-ragged lines (generally the default)
+% - include a manual \break to ensure application at line start
+% - misbehave if called more than once at the same line start
+
+% the parameters of the (full) pseudoIndents function are:
+% 1: name-tweaks
+%      usually omitted; accepts replacement \markup for instrument names
+%      as an ordered list; starred elements leave their i-names unchanged.
+% 2: left-indent
+%      additional left-indentation, in staff-space units; can be negative,
+%      but avoid a total indentation which implies (unsupported) stretching.
+% 3: right-indent
+%      amount of right-indentation, in staff-space units; can be negative.
+%      - not offered by the (reduced) pseudoIndent function
+
