     unexpand - convert spaces to tabs


SYNOPSIS

     unexpand [-a]

DESCRIPTION

     Unexpand replaces spaces in the named files with  tabs.   If
     no files are listed, stdin is given.  The -a flag is used to
     force all sequences of spaces to  be  expanded,  instead  of
     just leading spaces (the default).
