# Format a help string so that it looks pretty when

# the user executes "script --help". This macro takes three

# the COLUMN which is a string of white spaces which leads to the

#

# The resulting string is suitable for use in other macros that require

# a help string (e.g. AC_ARG_WITH).
|

#

# Here is the sample string from the Autoconf manual (Node: External

# "--with-readline", while the RHS is "support fancy command line
|
||||
# editing".
|
||||
#
|
||||
# If the LHS contains more than (COLUMN - 3) characters, then the LHS is
|

# terminated with a newline so that the RHS starts on a line of its own

# ----------------------------------

#
|

# Format a help string so that it looks pretty when
|
||||
# the user executes "script --help". This macro takes three
|
||||
# arguments, a "left hand side" (LHS), a "right hand side" (RHS), and
|
||||
# the COLUMN which is a string of white spaces which leads to the
|
||||
# the RHS column (default: 26 white spaces).
|
||||
#
|
||||
# The resulting string is suitable for use in other macros that require
|
||||
# a help string (e.g. AC_ARG_WITH).
|
||||
#
|
||||
# Here is the sample string from the Autoconf manual (Node: External
|
||||
# Software) which shows the proper spacing for help strings.

|

#
|

# A help string is made up of a "left hand side" (LHS) and a "right
|
||||
# hand side" (RHS). In the example above, the LHS is
|
||||
# "--with-readline", while the RHS is "support fancy command line
|
||||
# editing".
|
||||
#
|
||||
# If the LHS contains more than (COLUMN - 3) characters, then the LHS is
|
||||
# terminated with a newline so that the RHS starts on a line of its own
|
||||
# beginning with COLUMN. In the default case, this corresponds to an

# LHS with more than 23 characters.
