CDBS-EDIT-PATCH(1)                                              CDBS Documentation                                              CDBS-EDIT-PATCH(1)

NAME

       cdbs-edit-patch - create or edit a CDBS simple-patchsys.mk patch

SYNOPSIS

       cdbs-edit-patch patchname

DESCRIPTION

       cdbs-edit-patch  creates  or edits patches for use by the CDBS simple-patchsys.mk patch system.  For more information about CDBS please see
       the documentation under /usr/share/doc/cdbs/.

       When patchname exists, cdbs-edit-patch will set up a temporary working source tree, apply all patches up to and including patchname in lex-
       icographic  order,  and  spawn  an  interactive shell for the developer.  The developer can then edit files in this working tree.  When the
       developer is done and exits the shell, cdbs-edit-patch updates patchname to reflect the changes made.  To abort the process from the inter-
       active shell, exit with a nonzero exit value.

       When patchname does not exist, cdbs-edit-patch will assume that a new patch should be created.  As with the above scenario, cdbs-edit-patch
       will first create a temporary working source tree and apply all patches up to the new patch in lexicographic  order.   When  the  shell  is
       quit, cdbs-edit-patch will create patchname.
