compver(F) 19 June 1992 compver(F) Name compver - compatible versions file Description compver is an ASCII file used to specify previous versions of the associ- ated package which are upward compatible. It is created by a package de- veloper. Each line of the file specifies a previous version of the associated package with which the current version is backward compatible. Since some packages may require installation of a specific version of another software package, compatibility information is crucial. For example, a package called ``A'' requires version ``1.0'' of application ``B'' as a prerequisite for installation. If the customer installing ``A'' has a newer version of ``B'' (version 1.3), the compver file for ``B'' must indicate that ``1.3'' is compatible with version ``1.0'' in order for the customer to install package ``A''. Note The comparison of the version string disregards white space and tabs. It is performed on a word-by-word basis. Thus: ``Version 1.3'' and ``Version 1.3'' would be considered the same. Example A sample compver file is shown below. Version 1.3 Version 1.0
