Description

Take the following example:

if {"$v" equals "a"} {
  do something a
} {
  if {"$v" equals "b"} {
    do something b
  } {
    if {"$v" equals "c"} {
      do something c
    } {
      do something others
    }
  }
}

By introducing the commands shell:elif and shell:else, this can be simplified as follows:

if {"$v" equals "a"} {
  do something a
} elif {"$v" equals "b"} {
  do something b
} elif {"$v" equals "c"} {
  do something c
} else {
  do something others
}
