NAME

       ospam - An SGML System Conforming to International Standard ISO 8879 --
       Standard Generalized Markup Language. An SGML Extended Facilities  sys-
       tem  conforming  to  Annex  A  of Internation Standard ISO/IEC 10744 --
       Hypermedia/Time-based Structuring Language.


SYNOPSIS

       ospam [-CeghilprRvx] [-alinktype] [-Aarchitecture]
             [-bbctf] [-ccatalog_file] [-Ddirectory]
             [-ffile] [-mmarkup_option] [-oentity_name]
             [-wwarning_type] [sysid...]



DESCRIPTION

       ospam (OpenSP Add Markup) is an SGML markup stream  editor  implemented
       using  the  OpenSP  parser. ospam parses the SGML document contained in
       sysid and copies to the standard output the  portion  of  the  document
       entity  containing  the document instance, adding or changing markup as
       specified by the -m options. The -p option can be used to  include  the
       SGML declaration and prolog in the output. The -o option can be used to
       output other entities. The -x option can be used to expand entity  ref-
       erences.


       The following options are available:


       -aname, --activate=name
              Make doctype or linktype name active.


       -Aarchitecture, --architecture=architecture
              Parse with respect to architecture architecture.


       -bbctf, --bctf=bctf
              Use bctf bctf for output.


       -csysid, --catalog=sysid
              Use the catalog entry file sysid.


       -C, --catalogs
              This has the same effect as in onsgmls(1).


       -Ddirectory, --directory=directory
              Search directory for files specified in system identifiers. This
              has the same effect as in onsgmls(1).


       -e, --open-entities
              Describe open entities in error messages.


       -Emax_errors, --max-errors=max_errors
              Exit after max_errors errors are encountered.


       -ffile, --error-file=file
              Redirect errors to file. This is useful mainly with shells  that
              do not support redirection of stderr.


       -h, --hoist-omitted-tags
              Hoist  omitted  tags out from the start of internal entities. If
              the text at the beginning of an internal entity causes a tag  to
              be  implied,  the  tag  will usually be treated as being in that
              internal entity; this option will instead cause it to be treated
              as being in the entity that referenced the internal entity. This
              option makes a difference in conjunction with  -momittag  or  -x
              -x.


       --help Display a help text and exit.


       -iname, --include=name
              This has the same effect as in onsgmls(1).


       -l, --lowercase
              Prefer  lower-case.  Added names that were subject to upper-case
              substitution will be converted to lower-case.


       -mmarkup_option, --markup-option=markup_option
              Change the markup in  the  output  according  to  the  value  of
              markup_option as follows:

              omittag  Add  tags that were omitted using omitted tag minimiza-
              tion. End tags that were  omitted  because  the  element  has  a
              declared  content of EMPTY or an explicit content reference will
              not be added.

              shortref Replace short references by named entity references.

              net Change null end-tags into unminimized end-tags,  and  change
              net-enabling start-tags into unminimized start-tags.

              emptytag Change empty tags into unminimized tags.

              unclosed Change unclosed tags into unminimized tags.

              attname Add omitted attribute names and vis.

              attvalue Add literal delimiters omitted from attribute values.

              attspec Add omitted attribute specifications.

              current   Add   omitted  attribute  specifications  for  current
              attributes. This option is implied by the attspec option.

              shorttag Equivalent to combination of net,  emptytag,  unclosed,
              attname, attvalue and attspec options.

              rank Add omitted rank suffixes.

              reserved Put reserved names in upper-case.

              ms  Remove marked section declarations whose effective status is
              IGNORE, and replace each marked section declaration whose effec-
              tive  status  is  INCLUDE by its marked section. In the document
              instance, empty comments will  be  added  before  or  after  the
              marked  section  declaration  to ensure that ignored record ends
              remain ignored.

              Multiple -m options are allowed.


       -n, --error-numbers
              Show error numbers in error messages.


       -oname, --output-entity=name
              Output the general entity name instead of the  document  entity.
              The  output will correspond to the first time that the entity is
              referenced in content.


       -p, --output-prolog
              Output the part of the document entity containing the SGML  dec-
              laration  (if  it was explicitly present in the document entity)
              and the prolog before anything else. If this option is specified
              two  or more times, then all entity references occurring between
              declarations in the prolog will be expanded; this  includes  the
              implicit  reference to the entity containing the external subset
              of the DTD, if there is one. Note that the SGML declaration will
              not  be  included  if it was specified by an SGMLDECL entry in a
              catalog.


       -r, --raw
              Don’t perform any conversion on RSs and REs when outputting  the
              entity.  The  entity  would  typically  have the storage manager
              attribute records=asis.


       -R, --restricted
              This as the same effect as in onsgmls(1)


       -v, --version
              Print the version number.


       -wtype, --warning=type
              Control warnings and errors according to type. This has the same
              effect as in onsgmls(1).


       -x, --expand-references
              Expand  references  to entities that are changed. If this option
              is specified two or more times, then all references to  entities
              that contain tags will be expanded.



BUGS

       Omitted  tags are added at the point where they are implied by the SGML
       parser (except as modified by the -h option); this is often  not  quite
       where they are wanted.


       The case of general delimiters is not preserved.


       Incorrect  results may be produced if a variant concrete syntax is used
       which is such that there are delimiters in markup to be added that have
       a prefix that is a proper suffix of some other delimiter.


       If  an  entity reference in a default value uses the default entity and
       an entity with that name is subsequently defined and that default value
       is  added to the document instance, then the resulting document may not
       be equivalent to the original document. ospam will give a warning  when
       the first two conditions are met.
