# [string trim] feels better than [lrange] proc heredoc {body} { return [string trim [uplevel 1 [list subst -nocommands [join [lmap x [split $body \n] {string trim $x}] \n]]]] }

This generates: ERROR: [file tail /home/cecil/bin/testing.tcl] ?--auto-update? --rolback PIPTYPE PIPPACKAGE While my version generates: ERROR: checkPipPackages.tcl ?--auto-update? --rollback PIPTYPE PIPPACKAGE I also find my version more clear and I find easiness to understand important.

What does what I want: set usageError "ERROR: [file tail ${argv0}] ?--auto-update? --rollback PIPTYPE PIPPACKAGE" Sadly formatting gets lost in replies. :'-(
