%global common_description %{expand:
E00compr is an ANSI C library that reads and writes Arc/Info compressed E00
files. Both “PARTIAL” and “FULL” compression levels are supported.

This package can be divided in three parts:

  • The ‘e00conv’ command-line program. This program takes a E00 file as input
    (compressed or not) and copies it to a new file with the requested
    compression level (NONE, PARTIAL or FULL).

  • A set of library functions to read compressed E00 files. These functions
    read a E00 file (compressed or not) and return a stream of uncompressed
    lines, making the E00 file appear as if it was not compressed.

  • A set of library functions to write compressed E00 files. These functions
    take one line after another from what should be a uncompressed E00 file,
    and write them to a file with the requested compression level, either NONE,
    PARTIAL or FULL.}

%description %{common_description}

This is a metapackage that installs both the command-line tools
(e00compr-tools) and the libraries (e00compr-libs).
