Usage: info unwinder [LOCUS-REGEXP [NAME-REGEXP]]
LOCUS-REGEXP is a regular expression matching the location of the
unwinder. If it is omitted, all registered unwinders from all
loci are listed. A locus can be 'global', 'progspace' to list
the unwinders from the current progspace, or a regular expression
matching filenames of objfiles.
NAME-REGEXP is a regular expression to filter unwinder names. If
this omitted for a specified locus, then all registered unwinders
in the locus are listed.c s t t| ��dtj� d S )Nz

LOCUS-REGEXP is a regular expression specifying the unwinders to
enable. It can 'global', 'progspace', or the name of an objfile
within that progspace.
