defoma-subst is a tool to create/edit a rulefile of Defoma font substitution system. This system makes a certain font provide an user-specified id. Rulefile exists in order not only to specify such ids but also to have more similar fonts containing same characters substitute for the id.

Following is the form of rulefile.

# comment..
# comment..
Helvetica --GeneralFamily SansSerif --Shape NoSerif \
  Upright --Weight Medium --Charset,* ISO8859-1
Helvetica-Bold --GeneralFamily SansSerif --Shape NoSerif \
  Upright --Weight Medium --Charset,* ISO8859-1

In this example Helvetica and Helvetica-Bold are need-to-be-substituted ids, and following hints represent information of these two fonts. The asterisk added to Charset hinttype with comma means Charset is required to match.

SH COMMANDS

new-rule

Create a new rulefile rulename.subst-rule under /etc/defoma. additional-lines are added to the file as comments or default rules. Quote each rule or comment with single or double quotations.

edit-rule

Edit the rulefile specified by rulename. After editting, modification is reflected to the related Id cache. In other words, new ids would be added provided by substitutive fonts to the Id cache if a rule is added, and registered ids would be removed from the Id cache if a rule is removed.

add-rule

Add one or more rules specified by rules to the specified rulename. Quote each rule with single or double quotations.

remove-rule

Remove one or more rules specified by rules from the specified rulename. Quote each rule with single or double quotations.

check-rule

Check if the rulefile specified by rulename exists. It returns zero when the rulefile exists, and non-zero (actually one) when the rulefile doesn't exist.

-t

Exit with true value (0) even if error occurs.

-v

Verbose output.

-d

More verbose output.

-q

Quiet output.
