DESCRIPTION

       The package textutil::trim provides commands that trim strings using arbitrary regular expressions.

       The complete set of procedures is described below.

       ::textutil::trim::trim string ?regexp?
	      Remove  in  string  any  leading	and  trailing  substring according to the regular expression regexp and return the result as a new
	      string.  This is done for all lines in the string, that is any substring between 2 newline chars, or between the	beginning  of  the
	      string  and  a  newline, or between a newline and the end of the string, or, if the string contain no newline, between the beginning
	      and the end of the string.  The regular expression regexp defaults to "[ \t]+".

       ::textutil::trim::trimleft string ?regexp?
	      Remove in string any leading substring according to the regular expression regexp and return the result as a new string. This  apply
	      on  any  line in the string, that is any substring between 2 newline chars, or between the beginning of the string and a newline, or
	      between a newline and the end of the string, or, if the string contain no newline, between the beginning and the end of the  string.
	      The regular expression regexp defaults to "[ \t]+".

       ::textutil::trim::trimright string ?regexp?
	      Remove in string any trailing substring according to the regular expression regexp and return the result as a new string. This apply
	      on any line in the string, that is any substring between 2 newline chars, or between the beginning of the string and a  newline,	or
	      between  a newline and the end of the string, or, if the string contain no newline, between the beginning and the end of the string.
	      The regular expression regexp defaults to "[ \t]+".

       ::textutil::trim::trimPrefix string prefix
	      Removes the prefix from the beginning of string and returns the result. The string is left unchanged if it doesn't  have	prefix	at
	      its beginning.

       ::textutil::trim::trimEmptyHeading string
	      Looks  for  empty  lines (including lines consisting of only whitespace) at the beginning of the string and removes it. The modified
	      string is returned as the result of the command.
